The el-cheapos I mentioned failed in way that makes them unusable and unreliable. Every time after a week or so, they'll give me wrong readings. I almost threw away my Arduino Uno board because while troubleshooting it wasn't giving me any reading on half of the pins(yes exactly 50% of the pins). Gave it to my friend who next morning reported that his el-cheapo was giving reading on all the pins. The same things goes for resistors, most of the time it gave me an alternating resistance(like come on that thing ain't transistor) varying every second.
I don't know about your accuracy needs or what your project requirements are. Since you mentioned in your original post that you are a newbie and engineering student, I can guess a thing or two.
You mentioned Arduino working and also your el-cheapo meters not working for a day or two. Are you talking about the absolute dirt cheap $2 meters you get anywhere like this? (

If you are referring to those, I don't know about quality of those meters. But Aneng or Meco or UniT meters shouldn't fail on you that easily. In fact, I would check why your multimeters are failing so frequently on you. I had a similar multimeter before and it used to do an alright job.
I am using my Aneng and HTC DM-97 for about an year now. I tinker with basic electronics circuits (analog amplifiers, oscillators etc) and Arduino. I didn't have any complaints with them. Even the capacitor calculations, diode drop voltages etc, are very accurate (10mv precision).
So I don't have a huge complaint when it comes to their durability and accuracy. Reliability, I don't know if 1 year is good enough for you. For me, a $20 gadget working for a year or two, I wouldn't mind replacing that.
Also, based on your strong desire for BM235, I guess you made up your mind for buying it. Trust me, once you have locked your sights on a thing, many times we can't see positives of other options.
(I am being judgmental but I am saying from my own experiences. I fall in that situation often too.) You can do what I do now - Go and buy that damn BM235 and focus on getting a circuit or two out. Don't sweat over it. If you want a practical advise - just buy an Aneng, Uni-T or Fluke and just get back to doing business.
And if you really want a quality product with reliability why not buy following?
https://www.amazon.in/Fluke-Multimeter-Calibration-Certificate-Warranty/dp/B07B3WCV34/ref=sr_1_3_sspa?s=industrial&ie=UTF8&qid=1529656829&sr=1-3-spons&keywords=fluke+multimeter&psc=1It is Rs. 7850 (USD 115) with NIST calibration certificate. So you can trust that it is accurate. 4000 counts. Fluke is very reputable brand so I assume reliability and durability is going to much better than cheaper Chinesium products.
I also venture in photography, many times I feel that the lens in my hand is not doing a good job and taking bad pictures. If and only if I get that new lens with wider aperture, I will start making better pictures. Always and always it is me who doesn't use the full potential of the current camera and lenses. It is never the specific lens in my hand.
Just for your motivation (
https://keepdevelopingprojects.wordpress.com) this is the blog of a guy who won R&S fully loaded oscilloscope from Dave. He didn't have an oscilloscope earlier. And he made tons of awesome projects. You can do a lot of things by not buying the most expensive and most elaborate things...
Please don't be offended by my comment. I am telling you as a friend who spent ton of money on things which were not absolute mandatory. Luckily I earn my own money and burn... so it is bad but not as bad as burning parents money.
Also, hey karkoon could you let me now from where did you buy your oscilloscope from. Are there any official distributors in India?
I bought it from AliExpress last May. I can't find my oscilloscope there anymore. You can still buy Hantek and Rigol on AliExpress.
I enquired in India related to this and there are two dealers to whom I contacted:
http://www.scientificindia.com/Test-Measuring-Instruments/Oscilloscopes.aspxThese guys brand Siglent oscilloscopes as their own. There is no difference in features etc. You also get support.
http://www.sweeyatech.com/oscilloscope.htmlThese claim to be official distributors of Siglent in India. I ordered my scope from AliExpress and shipping was FedexIE. I paid close to 27k for SDS-1202X-E. I got quote of 36k from Siglent distributor in Bangalore.
Now in hindsight, I would go and buy Rigol 1054z. Not because SDS-1202X-E is bad but Rigol has 4 channels and if you are working under 50Mhz (which I almost always do... even my signal generator is 25Mhz). You can get away with that bandwidth. Rigol can be hacked to 100Mhz, but I wouldn't count on it. The most important aspect for me between SDS-1202X-E and 1054z would be the sampling rate and it is same as 1G/s for both. So I am very comfortable with Rigol too! You can get that from AliExpress and after paying all the duties you will still save 5k at least.
Good luck!
