I have it narrowed down to four choices:
1. mid 90's Cannondale R2.8 at consignment at local bike shop. Owned by older adult who gave up road bikes and went to a hybrid. It has 105 ergo shifters.
2. 94 Trek 1220 nearby found on Craigslist. Original owner is selling it. Price is $250. Trek 1220 Bicycle great condidtion
3. 01 Trek 1000 Alpha found on Craigslist. Has new cassette and chain. Price is $160. Ad is deleted now.
4. Year unknown Shogun 1000 with 105 bar end shifters, Nitto bars and new big ring $250. Offered by someone who was interested in Bianchi.

Which of the four should I pursue? Any recommendations?
