Allez is a popular bike. Whether it is worth it or not is a question ONLY YOU can answer, based on your projected uses of the bike. The Allez will be a twitchy-steering, race-bike type ride, and will be an attractive target for thieves.

Since the Allez doesn't allow fenders, you'll have a "racing stripe" up your back in all wet weather. You'll also have a time mounting saddlebags or baskets, if needed. If you want to eventually race, the Allez is a bargain. If you want to commute, the Allez SUUUUUUUUUUUUCKS!

Don't let the bike salesmen OR the self-styled "experts" on bikeforums.com (including ME!) tell you what to buy. Instead, analyze your needs, and buy the bike that is suited to those needs. In the end, YOU have to live with the purchase you make, day in and day out. Focus first on what you need - then on what you want.
