Looking for a BC ps3 but...?

Pretty much any PS3 that is not a slim version is backwards compatible. The 20 GB, the 60 GB, and the 80 GB are the only versions you can get that are BC. you can buy them on Gamestop.com refurbished, and you can buy some new ones on Gamestop, and Wal Mart, but they no longer make new 20 GB versions. You can also go onto Playstation.com, and find out what games are compatible, because even though your PS3 may be Backwards compatible there are some games that will not work with it. I don't know if you own a PS2, or a PS1, but if you get a new PS3 you can buy games from the Playstation Network, and download them onto your PS3. If you don't like any of these options you can buy new PS2's at Wal Mart for $100, and you can buy them used at Gamestop for $60. I hope I was helpful.
