Well. Let me put it this way: I spent a little over $100 on the fixed gear I'm riding. I will likely put a little more into it to upgrade bearings, bars and the like... I'm using a Firenze 12-speed frame (throw away, it's quite literally worth nothing if you do a little research on it) and some cheap ebay wheelsets. Weigh in? 23 pounds. Not bad for a bike that cost me slightly over $100, right?

So in my opinion, if it's your first fixed (this is mine) don't drop a ton of cash on it. In the future you might want to upgrade to that flashy new bike (I know I will eventually). To start? Nothing wrong with a totally worthless conversion

Edit: Oh you bought the capo, good choice, Cannondale will likely be my purchase when I eventually upgrade.
