Update:
I checked the LBS near work. Honestly, I like the guys in this store better than the shops near my house. But it's in the city, about 45 minutes away. Drat!

The Eros has the same exact frame, just different components. This salesperson thinks I'd need a smaller frame, like a 49. I didn't have time to ride anything here. Funny, since the other place did some measurements. I'm kind of puzzled by this. One guy looks at me and says, "oh the frame was probably too big" and at the other place, where they took measurements and I rode their bikes, they didn't offer this. I'm suspicious

And the guy I just talked to said most of their bikes go out with triple chain rings, and that the whole "compact double" thing is kind of a he-man, machismo thing. Guess which store I'd rather plunk down my money in!
