OMGWTFBBQ! There are a lot of Pistas out there, but if you are going for boutique, the Madison isn't the right place to look.

The comment about brakes is right on.

I agree with others that for the mileage you are talking about a somewhat relaxed geo is a good idea. I don't think that this has come up yet, but I would steer away from bullhorns. I love the things for shorter rides, but I would want to be able to get into the drops for longer rides.

Lastly, don't forget how easily modifiable ss/fg bikes are. Geometry sort of a big deal, but you can more easily/cheeply screw around with a ss than you can a geared bike.
