It’s crazy, but half racks take up more space than some full racks.
1. Footprint of a 3’x3’ rack is just smaller than that half rack.
2. The big consideration: You lift inside the full rack, rather than in front of the half rack.

Here are a couple in the same price range from Vulcan and (cheaper) Titan.

The one consideration is plate storage. Peg storage (either facing backwards on the rear verticals, or sideways on all verticals) is ok, but can interfere with some lifts. Rolling storage is another option (in the rack when not using it).
