Also look at the Trek 7*00 FX models. I have a 7300FX, but if you can afford it go for the 7500FX or 7700FX.
I am not sure why so few people in this forum recommend Trek, I wonder if there is not some type of Microsoft syndrome going on (snobbish resentment towards the 800 lb gorilla of the industry).
That being said, I second the motion that the LBS is more important than the bike. The main reason I bought the Trek is because that is what my LBS sells. They are close by and their 2 year service plan is awesome (and probalby worth an extra 500 bucks). When I need a repair it is a short ride away, as opposed to putting the bike rack on the van, loading up the bike, and then driving 20 minutes to a shop.
