Talk to me about hitch mount bike racks

I just bought a fancy new carbon full suspension bike(yay!!) but I need to come up with a nice rack now. I was previously using a 2" Thule rack that has outlasted 4 vehicles, but this new bike just won't (and probably shouldn't) go on there. I want an upright style hitch mount rack to carry at least two bikes. Obviously Kuat, Yakima, Thule, but I'd rather not drop $900 on this thing. Does anyone have a good recommendation for a less expensive option? Thx in advance.
