I just bought the Specialized BG2 saddle. Having never sat on a saddle that I found "comfortable," I can honestly say "I feel very comfortable on this seat." Plus as far as good/decent saddles go, it was cheap. Only $40 at my LBS.

Only downside, you're not going to win any style points with this seat. It is ugly, but I think not having an RX for viagra by the time I'm 30 is worth riding an ugly saddle.
