I'm with bikingshearer. I'm an old cheap guy at heart, too, but I gotta draw the line somewhere. I like to have a sense of security while I ride--both terms of my own safety and that I'll be able to make it home with the bike intact. I wouldn't want to ride in fear that each bump in the road might lead to a surprise colonoscopy, and/or potentially damage to the rest of the bike in a resultant crash. As expensive as vintage Campagnolo posts are, they are still cheap in comparison to modern carbon or Ti Moots posts, and well worth the cost of peace of mind.
