1. The hobbyist with little or no scope experience ?
2. The young professional, say the EE student with limited resources ?

In both cases, it depends on what you can get.

Are you living in the same world as the rest of us ?
In 2 weeks I can something from anywhere in the world......1 week from China.
It's not about what you can get but instead the best instrument for today's and future use....they are not expensive.
The hobbyist might pick some CRO boat anchor use in their twilight years however to advise the EE's of tomorrow to get one is just downright irresponsible.

At absolutely no point did I suggest someone pick up an analog boat anchor instead of a digital oscilloscope, unless you get something for $10 and can't afford better.
And... we do not all all living in the same part of the world. In the United States, one can regularly get older (but not scary old) test equipment for a pittance. I suggested the 54600 series (particularly the 54622D) because there are a lot of them around (that series of scopes sold VERY well in this country), and they can often be had for very little - sometimes free. In much of the US, they can also be found locally, saving on shipping. In my opinion, they are one of the cheaper way to get a decent, usable scope. Maybe not competitive with a new scope, but better than a lot of the budget digital scopes from 10 or 15 years ago.
Furthermore... in the US, EE students are paying between $7000 and $70,000 per semester, and the intensity of the programs means that many (not all, but many) don't have time to work during the semester. For many students (again, not all, but many), $400 is hard to justify.

do they have enough time repairing? and getting unobtainium parts? or advices on repair from locals? retired person surely have...

Yup, these are the 2 real worlds and few here understand both.

No, it is not irresponsible. I will leave others to comment on whether a Siglent scope salesman is being "responsible" when they say that, or whether there is some other motivation.

You really are pitiful tggzzz, play the ball and not the man please.
If I sold any other brand, even the market leaders would you still challenge my views ?
--- End quote ---
Resorting to ad-hominem attacks instead of addressing the points made is widely regarded as a sign of someone undermining their own case.
Which brand you sell is irrelevant, of course, and your question represents an unsuccessful attempt to deflect the discussion.
Have I touched a sore point? It sure looks like it :)
--- Quote ---The days for commercial use of CRO's are gone pure and simple and a POV that you may not like but my nearly 10 years in business plainly displays otherwise and the conclusion I'd already arrived at before Siglent offered me NZ distributor.
I am very fortunate to see all levels of the NZ marketplace which unless you stand in my shoes you never will with some customers taking months to scrape enough together to purchase their first decent scope after also traveling down the road I went as a hobbyist with CRO's only to discover the obvious that unreliable old boat anchors are not worth the effort if you have limited time with your projects.....whom on earth needs to have to their fix tools before being able to use them ?
But no, you see a post from me and associate to a brand rather that respect my knowledge from the hard knocks road travelled to get here ..... pitiful.

None of those points address the points I made - and which you you chose to snip in an attempt to avoid them. Here are the points again, so you can have a second chance to address them...
Frequently during a professional career people will have to make do with what's already available because
* you need it now, not in a month's time
* money has to be used for other necessary equipment
* it won't pass the purchase request process
* it is back at base, not here in the field
* boss says you don't need it
* there is nothing that is capable of doing the jobI've seen all of those, and had to find workarounds.
Might as well get engineers to think creatively from the outset. That's not true for technicians, of course - and vive la différence!
H713:
Certainly the issue of purchasing systems and contracts is a painful reality.
This might come as a shocker to some, but labs that receive state/federal funding (no matter how innadequate that funding is) are somewhat limited in who they can buy from.
In many cases, it's a $2500+ Tektronix or use what already exists. "Free Market Capitalism", right?
