I will also second it. But be very careful when buying Vibraplane bargains at eBay. Old models have a rubber pneumatic piston that is not supported anymore by Kineticsystems. If you have a leak the only official alternative is replacing all the pistons of the table with current ones, at a cost around 50% of the cost of a new table.
Very good advice. I bought two used units on Ebay. Cheap at $400 each. I set about refinishing them, painting them black, etc. Neither works well. Kinetic Systems quoted $1500 to fix each one. They don't want to do repairs. They want to sell new ones. Sure enough, I bought two new ones at just more than the repair costs of the old ones. I would not buy used on Ebay again. These are fragile and the surplus equipment sellers sell them "as is" because they know they have problems. The other thing to keep in mind is that the Vibraplane's performance goes way up when they are properly pre-loaded close to the design limit to total weight of 275 lbs. You can get custom steel ballast plates made for them and it is well worth it.
