Thanks for the feedback! This won't be my only bike, as I currently have a nice bicycle that I use for recreation (I got in to bicycles over the summer thanks to boyfriend, alas I've moved and can no longer rely on his expertise!), so in this case "simplicity" is attractive to me (all though I am yet to understand the allure of fixed bikes). It seems that it wouldn't cost anything beside the possible expense of a chain cutter (after all, it's subtraction not addition, right?). Ah, well, I will make that decision when the time comes!
