In other news, thinking about buying one of these nashbar blowout gt gtr frames. Any reason not to get one for $75?

Edit: Appparently these have real weird head and seat tube diameters. Can anyone recommend a decent aluminum frame for cheap? Intended uses are going fast and cat 6 racing. I love the way my "track" bike handles. Here is the geo chart for that.
