If you are a beginner the last thing you want to do is buy something off of craigslist.

Go online, find a Big Shot, Pure fix , State, SE lager. Sole or Motobecane for 199 to 250 you are going to love it. They are very good values even though many on this forum will tell you they are junk. They are not I own 2 of those on my list I ride the living crap outta them and have no trouble. I have friends that have some of the others and they love them.
