Unless you browse around on eBay and find a first generation PS3 then you're out of luck buddy, but if your PS2 is still kicking then there shouldn't be an issue. The PS3 is a great console and the exclusives are awesome! Uncharted and Uncharted 2 should be reason enough to buy a PS3. There's also Metal Gear Solid 4: Guns of The Patriots if you're a MGS fan, and there's also LittleBigPlanet which is the best platformer in existence, inFAMOUS which is a pretty badass superhero game which was badass enough to warrant a sequel as one is currently in development. There's also God of War III, and the HD remakes of the first two God of War games. There's also some awesome games announced at e3 such as Twisted Metal, and LittleBigPlanet 2. Plus as a bonus you get a Blu-Ray player... So what are you waiting for? Go right this second and buy one!
