That Micsig is interesting but has a smell of the horrible FNIRSI 1013D. Seems to be mostly sold on Banggood, Amazon and eBay... not a good sign.
If they want to penetrate the "western" market they should really work with some established distributors (looks like they are with Saelig, it's a good start)
There are three reasons I say this :
- These distributors are established and care about their reputation and will not sell crap (at least they try not to). So as customers, it is a guarantee of a certain minimum quality level.
- Good luck trying to get warranty/repair from something you bought on Banggood or even Amazon. After the return window, Amazon will simply tell you "go talk to the manufacturer".
- I doubt school are going to buy from Banggood
And we all know the added value of some distributors (Tautech ?)
Also, I think the major appeal of the SDS1104X-U is its price. I think it's a "race the prices to the bottom" scope, for people who don't need high end specs.
Think like audio stuff, learning how to use a scope, and some basic digital signal debugging (I2C, UART, ...). My first contact with a scope was in high school, we don't need 5Gsps there.
The Micsig seems to be $500, the Siglent $400. This 25% more matters when you are a student, or when you have to buy 20 to fill a lab.
I remember when $100 was a reasonably big deal to me... but I was already doing electronics and using my TDS200. I would have happily kept the $100 more + VAT and used it for something else.
If I had to choose now, I'd totally go to the SDS1104X-U without any second look for the reasons above (assuming I was in the target market obviously)
