I've ridden the Specialized Sirrus, the Opus Fidelio, and a Diamonback one that I can't remember the model of. In my area there are a few choices, Walmart, Canadian Tire, or the specialty shops, which don't carry Trek, one of them in fact is Specialized only, though they have a few Giants. The bike shop that pretty much carries Specialized is the preffered place for me to buy it, the first reason is that they have a discount for those participating in charity bike rides and they also offer free annual tuneups for people who buy their bikes.
