They may just be cutting some corners, and they're probably not paying much in the way of shipping for the individual components coming to them, etc. And it looks like they're just making a few bucks on them. Keep in mind, just shipping that thing to a proxy and then to the US or UK would add a bunch to it, so it's probably not that far off what we're paying here and it's of questionable quality.
Also I think the word "stealing" is a bit harsh. They're well within their rights to do this. If someone else making or selling is offensive, then "open source" probably isn't the way to go. Plus this is a group buy, so it's not like someone is taking all these potential profits away from Komar & co. I think we should be excited that this thing we've been a part of is garnering interest outside this community.
I don't worry about other folks getting theirs first because I want to get the one that was developed and built here. There have been hiccups, but I'm excited about the quality of this thing.
