Despite what people will tell you on this site, that bbtuna thread with table pricing is NOT always relevant. Every market is different and some markets drive the price of a good table way past what these old foosers would consider reasonable. If you don't end up buying the table, take note of how long it takes to sell. It's a decent indicator of current demand.
That said, kgstewar is correct. It is a brown marble - the sturdiest Tornado ever built.
