My workbench is not great, but here is the one I want to get.

www.grizzly.com sells tools but also a really nice workbench, a set of metal legs and hardwood top. The metal legs can be bolted to the floor, different stringers that run on the back side can be bolted into place. You can also adjust the height from 30" to 36".

Look for item G9923 (metal legs) and G9919 (maple top)
