Looks like they've made only 2 machines... All pics are of the 7214, and the 3636.
The machines look decently designed, and the components used are also decent quality. The s/w has been used by other commercial machines (cnccrafter is one), and the package price is definitely fair.
I'd look into where the company "is at", and see if the feeling you get matches what you see. I'm betting that they've only built 2 machines. But those two look like they could be a good choice.
Hope this helps,
P.S. Ask 'em some technical questions, and see what they know...
Will they tell you how many they've built? If it's more than two, can you talk to the owners of the previously sold machines?
It's a WHOLE LOT easier to build a machine or two, and post "accessories" using the mfrs. published photos, to make your company look established and competent; than it is to build a sustained cnc machine building operation...
Note that I have NO idea what their reality is, I'm just going by my experience, having had a look at their website...
