As mentioned in another post of mine, I still have my heavy wood joinery bench. I am keeping it for the knocking around, and cutting. I am going Friday morning to Sears to get one of their 6' long workbenches that are 42" height. They will be 50% off (or so I hear). I plan on getting the butcher block top. Once in my shop I will level the whole assembly and top it with plate glass and a metal sheet so I can use magnets.

Granite is becoming real popular in the furniture building world. A decent number of jointers are now being sold with granite tables instead of steel because they stay flat, are slick and low maintenance. I would think that if you can get a piece of granite at a good price it would be a great work surface.
