If you're referring to Gunbroker, it's awful right now. I've watched 5 M4's be sold multiple times then the user "unregisters" I'm guessing when the buyer pays them. If it's too good to be true, it is.
The jedi buckle is sounds like a lousy design but once you see it in person, you'll be pleased. I don't see it getting snagged any worse than anything else and the amount of elastic stretch is simply amazing... They just work very well for me.
