I am a casual bike rider... last summer I had a Specialized Globe Sport which I rode about 30-40 miles every weekend. It was great, but I hit a financial hole and had to sell it

Well I'm back in the game, and I'm looking at some new bikes. I really didn't like the flat handlebar of the Globe... I definitely want a full-out road bike. My budget is $800.

I've been looking at the Specialized Allez... what's the difference between the regular, double, and triple? I understand the difference between the sport and the non-sport, but I'm still not sure if the additional upgrades are really worth the price for my situation. I'm also not sure if I should save some more bucks and go with the steel...

Any advice or other bike recommendations?
