Hey! So I can't recomment where to get one, but sure I can recommend you to purchase a ps3 rather than a ps2. I don't know if we can talk about this here, put "hacking" a ps3 is relatively easy and then you can install all ps3 and ps2 games you want. If you don't see yourself doing that, you can search for the first ps3 generation, in which you can use ps2 discs on it. It's rather easy to know, just search a ps3 with 4 usb connectors on the front. Take note that this model is more expensive than the other ones tho.

Of course I'd say buy both, from a collector's point of view (let's be real, both the ps2 and ps3 are gorgeous!), but if you just want to game, a ps3 is your go to!

Finally, in my experience, don't buy a broken ps3 to refubrish. Generally, repairing a ps3 is not definitive, that means that in X time (1 day, 1 month, 1 year...) the ps3 will break again. In my opinion, this doesn't deserve your time and resources.
