58eur/$67 for a DIY kit, ,comign with the crappiest plastic handle? To me, it seems very expensive, and a try of charging twice trying to get extra profit of the silicon crysis.
There isn't a design that's notoriously better than others., everything is just the same, don't get fooled by a fancy alluminium bezel.
The major changes come in the 3.3V regulation. Some KSGERs (2.0, 2.1, 2.1s.. uhh... I don't know which ones right now) use a cheap design where they convert 24V to 3.3V with a linear regulator, causing a lot of heat.
For some boards it's too much, the LDO overheats and causes weird behavior like random resetting. But the analog front end is, as far as I know, the same thing in all with minor changes.
Maybe some KSGER fanboys can advice you better, I just see a ton of money for a crappy design
I'd get a KSGER 3.1, Quicko T12, Quecoo T12-955, whatever is cheaper.
