I might be looking at a lugged Columbus SL frame this weekend - apparently a guy in my neck of the woods used to do some framebuilding & he's selling one of them, a road frame. It is quite cheap, less than $100, and might even been in my approximate size. What are some different things I should look for that might indicate potential problems with the frame? Any suggestions?
And, Columbus SL is the a second tier/second best steel, isn't it?
