We have three of
these and love them. They are the basic 72" x 36" inch butcher block tables.
You can start shopping
here and work your way down the product selector by clicking things on the left side. We select the 'Global Industrial' brand.
Personally there is no way I'd build tables if I could find the money to buy these.
If you are buying them through the school then there may be a dedicated account rep and might can give you a discount. We got three for just under 1 grand with the discount and avoided going for bids (missing the 1K number).
