I have a DS lite and some other things I am looking into trading in somewhere towards the cost of a PS3. Which model should I look for? I would like to get one of the ones that is still backwards compatible with games, especially my favorite series like Kingdom Hearts and MGS. If I can get a BW compatible one, I can throw in my PS2 towards the trade-ins. I am not super worried about the HD size, because from what I understand its stupid easy to upgrade the HD in a PS3 to a larger one.
In addition, which games should I start out with? MGS4 is a given
