'Phoenix Wright: Ace Attorney' for DS is awesome. And right now I'm playing Hotel Dusk, which so far looks very promising. Both are oldish, so provided you can find them, you can probably get em used for about $20 each.

Depends on the games you like but if I were to give a recommendation for PS2. I would say God of War and God of War I. These have a fantastic storyline, Great gameplay, Great graphics. They are just simply amazing. I have completed both of these title's and await God of War III for PS3. But like I say it all really depends on what you like. =)
