Hi Bob,
In my experience, Diamond tables have a higher resale value than any other new table on the market. For example, if you purchased a new 9 ft Pro Am for $5500.00 and you had that table delivered and installed for $1300.00 your only depreciation would be the wear and tear on the simonis cloth, wear on the balls, and any scratches or marks on the body of the table. Dymondwood is almost impervious to showing wear. That table will typically bring $3995.00 used or 75% of it's new value. Freight, delivery, installation and wear and tear are the only real costs you are exposed on.
In 2010 a friend of mine bought a 7 ft pro am at the Billiards expo in Valley Forge PA for $3500.00. He played on that table for 5 years, same cloth, and we just delivered that table to it's new home. He sold that table for $3200.00. The new owner had to put a new cloth on for $400.00 plus delivery and installation. In this case the seller got back $90% of his original investment. That doesn't even account for the wear he put on the cloth. The best thing about it was, the table with a new cloth on it looked like a brand new table!
Diamond tables are not cheap to buy, but they are cheap to own. The fact that they play fantastic is just another perk.... By the way, the table sold in one day.
