Thanks Jon! I'm actually thinking of going to my nearest bike shop, though they probably won't have anything I really like—but no big deal, right? Cycling isn't all THAT big down here (McAllen, TX), so there is currently only one bike shop in the city and they don't have much to choose from. Either way, something inexpensive will do for the meantime. That or I'll look on eBay for some sweet deals.

Again, thanks for the advice!
