I would also recommend looking into sites like Cragslist and other sites in your area like that if you are strapped for cash as there is always a deal to be found by someone willing to get rid of a perfectly good PS3 usually with some games. Most people are in the same boat as you and have mates that play more 360 but they have a PS3 and have decided to switch consoles and are looking for a way to make some extra cash by selling there PS3.

Hope the hunt for a affordable PS3 works out for you it is defiantly a good console to have.
