definatly buy a PS-2 because if you buy a pre chipped one from the site below for about the same as the shops you will be able to play all your PS-1 back-ups without the need for a Boot CD as the latest NEO chip is capably of this.

You can buy the Ps-2's from here

Ps-2 back-ups will require a boot CD to be able to be played.
