Nice idea for a topic Yojimbo.
I don't have a picture, but my rack is a pretty much just a cheaper version of the one in Yojimbo's picture. It's not strong enough for what I can squat, but I'm very careful. If you can squat more than about 400#, you might want to consider a higher quality (like the one in Yojimbo's picture). My rack concerns me a little when you put that much weight shoulder high. Mine only sold for $200 new, and I paid $75 so I can't really complain.
After breaking several more complicated benches (like the adjustable one w/ leg attachments pictured) over the years, I've settled on a simple flat bench. It's made by CAP, and sold for $47. I got it for $27 since the seat was ripped-up. A little duct-tape, and it's as good as new. They rip anyway after some use, so it doesn't bother me. The only catch with it is that the end of the part of the bench you lay on doesn't stick-up past its legs. This is a problem when using it in a rack, because you can't move the bench far enough back, due to the vertical bar in the middle of the back, so that you can support your head while benching. This gives me a terrible headache while benching, but it's better than having an another adjustable one break. Notice on Yojimbo's rack that the legs stick-out a few inches past the rear uprights to give you a little more room (unlike my cheap one). Just something too look for if you're buying a bench to use in a rack. Make sure your head is supported when benching.
Yojimbo, where's your fan or A/C? I've got a large (4' in diameter) belt-driven fan in my work-out room that really helps keep me going. I finally got A/C in my house a couple of weeks ago, so a big fan was a necessity.z
