Guys, you ever buy or recommend buying a cell phone on ebay? The price for new phones is way cheaper then thru say Amazon or Best Buy. For example I'm looking to get my girlfriend a replacement phone as hers got crushed and she's only a few months into a two year Cingular (whoops "New ATT") agreement. The Pantech C300 sells for $200 at Best Buy but I see a few ebay sites offering it unlocked for $120 plus $15 shipping or so. Supposedly these sellers have lots of positive feedback.
