Am I correct in assuming that you would get fitted for the bike BEFORE buying it? If so, then go for it! If not, you may end up with the same problem you had with the Dolce. Rather than continue to buy and then get fitted only to find out the bike is not the right fit, I'd suggest going to get a professional fitting and then shopping for your bike.

This was my experience (take it for whatever it's worth, if anything):

Tried out LOTS of bikes . . . finally went for a professional fitting on a "fit bike." Took in specs/geometries of the different bikes I was interested in and the bike fitter then matched my fit measurements to the bikes that would fit me. Keep in mind that his shop did not sell all the bikes I was interested in, and he did not pressure me to buy from his shop. In fact, I ended up with a bike from a different shop.

At the time, I was not interested in Bianchis although his shop carries them. However, I knew I would be riding a Bianchi on a summer tour. He pulled up my bike fit measurements and let me know what size and model Bianchi I'd need (I had two models to choose from on this tour). He also told me that I'd need a different size stem to make it really fit, so I bought that from him and brought it along for the tour. Much better than hoping the tour people would guess the correct fit . . . I wanted to enjoy myself on our daily rides and not end up in pain!

Good luck to you in finding a new bike! I believe you CAN find a good deal through e-bay or whatnot, but you need to know sizing, etc. first . . . unless you want to go through the hassle of returns . . . or, maybe you'll just luck out and the next bike will fit like a glove!
