I have the rogue S2 rack and it's awesome. High Quality, great foot print for my single garage.
I've seen both the Gymdirect and Urban RX racks; they are bigger than my s2, they felt heavy duty and would be able to handle anything I could throw at them. There are a bunch of folks using muscle motion or force USA racks which are all coming out of china, so I don't think it's something to concern yourself about.
Gymdirect have a solid reputation.
I think Sam's fitness also do an ironmaster half rack (USA brand, China produced) you could look at for $750 or a German squat rack for $1.5k
Iron Edge did the same rack for $1.7k
