I bought a used Tournament table a year and half ago it was, by far, the best deal. I got it from Charles at TOrnado Foosball. As was mentioned already, it was cheaper than a new coin-op and some higher end new tables. It has already been assembeld, tested and used by pros. Belive me, you can tell - no bent rods, no warped playfields, etc.
On my table, there were virtually no visible signs of wear. The only issue was the handles were wood and had tape residue on them (I don't use wraps) and that was kind of gross. I replaced the old wood handles with the new handles, set the thing to free play (explained on many other threads) and I have a table that is going to outlast me. I also made other changes when the T-3000 kit came out last year. I mean, seriously, this thing weighs 350 pounds and is built like a tank. My kids play on it with me so it gets a good workout.
Just my two cents from having been down this road.
