They are actually well supported in terms of sales - robotshop sells it, trossen robotics sells it, and so does robotsavvy
So they don't seem terribly "iffy" in that sense, but their forum, which is actually hosted by robotsavvy and not them, only has 1 page worth of q's, most of which refer to high level stuff. Perhaps it's because only pros have used this dev platform, although I did get some answers to a few basic questions I had as well on there.
