well 2 things...first, you can look for obvioius external issues with good close up pictures or you can ask them and hopefully they will know...from the outside, the only obvious thing would be a crack or part of it chipped off
I didn't say anything about the men but I am assuming they are all new or like new (that means to me no visible cracks) - men are about $5 a piece so it can add up fast if a bunch of them are bad...nice if they have a few extra because ideally you would like to have 3 black and 3 yellow back up and if you get down to 1, reorder 2 more that way you don't run out at that crucial time
another thing about men...it may appear that on the outside the men are fine and that is step one but the reason I say new or like new is because there may be old men on there that are whole and not broken which on the surface seems fine - however, the foot of the man has grooves and if a man is played on long enough, these grooves wear down...
I was having control problems on my table and it didn't dawn on me that I had practiced enough to wear the front toe of my man almost flat...I put a new man on there and it was like getting a brand new table...so, if you can't see the foot, ask the person you are buying it from...or plan to change at least the center man on the 3 bars both 2 bars and probably the near man on the 5 bar
on rods...all rods need to be AT THE VERY LEAST straight no bow at all...a rod with bow can not be straightened...you can live with it and play on it like you do at a bar but there is no reason your home table, which will become your baby, should have bent rods...rods at $32.5 each really add up...I would be willing to bet that the 2 bars are almost for sure bent unless they were just changed and a good chance the 3 bar is as well
this is okay because you are buying a 10-12 year old table but you need to factor in the cost when buying the table
and if you can get all new heat-treated rods on the table, they will last nearly forever and they play much much better...best single improvement to the table in at least 15 years...very very hard to bend them out of shape, they are smoother, and they take less lube to keep in tip top shape
I have a Rosewoood T2000 and replaced the 2, 5, and 3 bars and it was like a new table...one day I will replace the others as well but for now, my practice is covered
