I had the same dilemma a while ago. I've always wanted a roadbike, but wasn't quite sure that I would be able to keep up the interest. – So naturally I wasn't willing to invest a fortune, without having tried it out first. – It's not quite enough to be a Tour de France fan, if you're going to invest that much money in a bike, you've got to be sure, that it's something you wan't to pursue for at least a while.
I've always found the Bianchi bikes fantastic, but the price is up there as well:

So instead I found a really good offer at a danish webshop (Coop category: Cykler). The bike had pretty much everything I was looking for and it only cost 500$. I still have the bike and it performs great. So even though I'm sure that it's something that I'm going to pursue for a long time, I'm holding on to my discount bike, until it breaks. Then maybe I'll be looking at the Bianchi :-)
