Here's a picture of what has passed for a work bench in my garage for the last 30 yrs.
My brother said he'd pay for the lumber as a house warming gift so I could build one, but we found this while contemplating how big to build one. It was being surplussed by our then current employer and had been used in an electrical shop. When he found we could get it for $40 it was a no-brainer buy. It came with the power strip you see running across the back. The top can be taken off and flipped over to re-new the surface. It weighs about 400 lbs and the drawers are full depth and it measures 8 ft long by 3 ft deep. The top is solid masonite. As you can see, it is an awesome work space, when you can find space to work.
