I have the 2.1 '06 model and love it. I paid the regular price for it so it wasn't cheap, even though I got in well before the real riding season this year. But I compared it to a couple of discounted 05 models, other middle price 06 models, as well as the women's version of the Specialized Allez (what my hubby got). Unfortunately, the price differential between the Spec. men's and women's was significant and that wasn't in near my target price. I felt the 2.1 was the best combination of features.components at that price point (it was actually a little more than I'd been thinking to spend, but I haven't regretted it at all), and it fit well. The rest of the bikes didn't feel as crisp. I wasn't a huge fan of the pink but the black really mutes it nicely.

I would say if it's not a bank-breaker, go for the better bike - it's a long term item from which you'll get lots of use, especially if you are happy with it.
