I need a new cell phone

Ok guys, I am looking for a new cell phone. I don't want to spend more than a hundred dollars because I will only have it for a couple months at the most. I don't need an mp3 player or any PDA features, just a phone (bluetooth is ok). If you are selling one, I would like to see it. If you have a suggestion, I would love to hear it (maybe craigslist or ebay links?). Thanks!
