I was at Sam's yesterday in the automotive section. I spotted a work bench with a 1.75" thick Maple top 72"x25". The legs and supports appeared to be 3" square steel with that "Fish Eye" silver and black paint. Looks Heavy Duty. It was constructed such that it looks like it would be easy to add a storage cabinet underneath. $199 locally, online $171.86. I think it would be hard to build one cheaper.
