Best power rack under $500?

Bought a house, there's a nice 20x15ft structure in the back that is perfect for a gym, so Im thinking of canceling the membership and building up something with everything I need and nothing I dont.

Already have plates, bars and a couple machines on order, but I'm having trouble wading through the muck of affordable power racks. Lots of options out there and I'm not really sure what to trust.

Any experience with power racks around the $500 price point? Can go as high as $750 but would rather not. Safely benching and squatting heavy while alone is a must here.
