Some NIB games can go on location and get the shit kicked out of them for 10k plays and need nothing other than rubbers. SW Pro is an excellent choice. I've had one on location since I bought it new. I'd have to look, but it has around 8k-10k plays and I literally have not had to fix anything. You should be able to go years without have to do much at all, especially SW Pro. Newer Sterns have been very good to me. Depending on the batch you may have to replace the coil stops or flipper buttons though.
