Want to buy:

I'm looking for a frameset or a complete bike that is made of anything other than a total beater. Pretty much, I want something better than my Puch. I'm 5'9 so probably a 54-56cm frame would work. I guess i'll be willing to spend up to 150 or possibly 200 shipped though i'd prefer to spend less. I'm located in Amherst, MA. Thanks!
