Maker Select v2 is great stuff, it's basically a i3 clone. It usually sells for around $300, roughly $250 when on sale. I don't really trust the majority of the chinese stuff out there. It's either a fire hazard, takes weeks to get to USA, or proprietary stuff you can't alter in any way. I believe the Prusa i3 MK2s is pretty cheap right now. If you want to spend the big bucks, basically any Utilmaker is going to be great.
