Yags,
that is for sure NOT a T3000 - that is a T2000 ... not all of them have warped playing surface...I play on one, and am going to play on it tonight, which is warped but I have a friend who has basically the same table, the one you describe, and the surface is not warped and it is great play...nothing wrong with this table as long as the surface isn't warped
the cross-hatch is the on the front of the man...on the old design man, there are grooves on the foot...on the back they go back and forth in a plaid pattern but on the front, it only goes half way up and the other half only has grooves in one direction (the top half)
the new foot is most easily seen by this change of the cross-hatch but it is not the only change...the front edge of the man is different...i wont' bore you with the details right now but trust me, if you have wooden handles and the table is more than a month old, you have a T2000
