I think the main concern here is whether your LBS thinks that they are in good condition. The bottom bracket will be a sealed unit, so you won't be able to inspect bearings or cups. However, as someone that had used Campy parts exclusively for many years, they generally do last quite some time and with very few problems. FYI: front deraileurs generally last much longer than their rear counterparts . If you are able to take the bottom bracket spindle in your hands and roll it in your fingers... listen for any gritty sounds and generally how smooth it seems to move. More than likely, you have found a good deal!!! Have fun!!
