I think you've come to the right place for validation! My DH just bought his third bike. A Surly disc trucker. I have two, a Dolce Elite for summer rides and a Jamis Aurora for commuting and the other nine months of the year up in the PNW, ha. So we have five now.

You've found some great bargains though. That makes it easier to justify!

We are doing Chilly Hilly Sunday. I was hoping the weather would be nice enough for the lighter Dolce...alas, it looks like it will be the heavier Jamis with the fenders and wider tires.
