that is a nice frame.
if you can find one of those, and you can use your $25 gift certificate towards it... do it!
seriously though, if you're thinking about the rush hour that much, and you really like it, go for it. $550 is pretty much the lowest you're going to get for an entry level complete fixed bike. unless you get the $350 mercier or windsor off ebay. the raleigh might hold up a little longer than those ebay bikes though.
