Brandosees, When it comes to old bicycles, you have to take the negative opinions along with the positive ones as both can have a positive effect on a project. Your Varsity is generally considered an entry level bicycle, despite yours and other's affection for them. The aluminum rims are a good modification, but I wouldn't go much further unless maintenance issues are included. Search for the gas pipe thread for ideas.
There is no list of C&V bicycles. There are simply too many brands and models, add to that few are still in OEM condition nor OEM equipped. Browse through this forum and read some comments on member's builds for good bikes.
