It's your choice. I loved my PS2. I wanna get another one as soon as I find a better job than the one I have now. If your remember, the PS was anything short of extraoridnary when it arrived. They hammered the chips on that bastard like they did the Miggy back in the day. Sony doesn't screw around with it's chipset. The PS2 can hold it's own for a few more years, believe me.
Do whatever you need to do, to make yourself happy. I don't currently own an amiga, but that doesn't make me any less an AMIGAN. :-D
