ps2 or psp

I got a dilema here. I currently own a ps3 40gb version. It cant play ps2 games.

So the question is should i buy a ps2? or a psp?

Im a huge final fantasy fan and ive played them all exept ff12, ff12 is the main reason why i want to rebuy a ps2. But games like kingdom hearts and god of war is games i never had a chance to play when i had a ps2.

Is it worth to rebuy a last gen console for a few classic games?

Or i can buy a psp.. the graphics are identical as the ps2 graphics but its handheld which is great. And got games like gow, ff crisis core. Which one should i buy?

Im a huuuge ff fan so if i would buy the ps2 i would also get ff10 which ive finished before but dont remember much from it.

If you only want FFXII, don't bother with a ps2. It was nothing special.

But i would stil reccomend a ps2 just because it has so many more great games than the psp does.
