Nah, just emulate it. The physical copies are way too expensive.
But! If you do get a PS2, well first make sure that it's a slim because the original fat ones suck and break and the slim ones are ****ing sexy and last forever, but anyway, keep in mind that all PS2s can also play PSX games. So you'll have access to all those oldass JRPGs too (and a copy of Parasite Eve is only like, what, twenty bucks? And I think FFVII is like ten or fifteen).
Although now that I think about it, if you already have a PS3, those can play PSX games too.
