Capo #1: Brooks Pro -- After almost 35 years and 50k miles / 80k km, the saddle is showing its age, but it is
very comfortable, and it looks great on the bike. I purchased it for $5 when the original owner gave up on it after the first two weeks (which are the hardest, so to speak

).
Schwinn: Brooks Team Pro -- Purchased used on eBay; delightful saddle.
Peugeot: Brooks Competition -- I dislike the tiny rivets which can snag a careless rider's shorts, but this is one very comfortable saddle, and its was only $20 on eBay. The Pro and Team Pro are much better-looking, but this one is ideal for my beater/commuter.
Bianchi: Serfas ARC -- Light and reasonably comfortable, but I prefer Brooks.
