I purchased the Rep Fitness 1000 rack with bench shipped for around $400. It has been outside for 2 years on a patio. The paint has faded, the black is slightly lighter. Daily use and it has not become wobbly yet. Stainless steel attachment bolts/nuts/washers, no rust. Bench is stable and has stayed level and flat. Its the best investment I have made towards supporting my training goals.
Good luck finding any fitness equipment now. I tried buying an incline/decline bench and could not find any online starting 4 weeks ago. Nothing on Amazon, local stores are closed.
