I'm going with a stainless table, too. It makes so much more sense than wood. Here's another alternative which happens to be the same price with free shipping. The only thing to think about is the weight rating. The one in the link below is rated for 330 pounds which will be cutting it close for my 13 gallon batches. I'll probably just add some diagonals or something if I feel it needs some more strength. Mine's definitely getting castors, too. Be aware that the legs and bottom shelves on these tables are usually not stainless, but galvanized or chrome plated steel. Just a heads up.
What are the dimensions of the Costco table?
