I can see how it can get very expensive very quick. At this point I know I'm nowhere near a 100 mi ride, at 40 miles my legs are getting ready to jut drop.
That bike in that link looks really nice but (and PLEASE PLEASE PLEASE bear in mind I'm a total noob when I ask this) it's two years older than my current model, does it make sense to change for this? It is certainly less expensive than what I wanted, so in that regard yes, I like it a lot.

I do not bike commute, I could, my office is around 6 mi from my house but the one time I did it I arrived all sweaty (I'm in Miami) so I never did it again. I could take the train and have a split commute also.

Elvo, thanks also for the chart, very informative and a bit discouraging also, ;-)
