What kind of old road bike do the rest of you have/still ride? What sort of problems have you had keeping it on the road?

Here is what I have, it's a 1984 Schwinn Peloton that was made for them by Panasonic it has a Columbus tube frame with Suntour group set rolling on Araya aero tubular rims. It has been a good old bike but the rear rim has developed some cracks around the spoke holes so I am getting a new one and the chainring is bent but it is 21 years old now. I can not believe I thought $800 was sooo much money when I bought it new back in 84.

This probably should be a new thread but where is the best source for Suntour parts?
