Don't blow off road frames for a budget fixed. For road use, which I expect is what we're talking about here, they can be just as good if not better than track specific frames/bikes. Track frames are pricey cos everybody wants one, they have toe overlap and are twitchy if you're not used to them. You can pick up a quality road bike for cheap (we're talking one with horizontal dropouts), strip the gearing off, swap out the wheelset and you have a cheap fixed. You can always upgrade some of the parts later. But they make a good place to start.
