No better lasers and the like. The erm... dodgee shops which do chips also sell PS2 component parts say if you bust your PS2 messing inside. They sell the standard laser (30003) and the R laser (30003R). The R laser won\'t fit in the standard PS2. It is an upgraded laser. Theres even more differences but I don\'t know them all but the R definatly means the PS2 has a upgraded laser along with other changes.
D3AD_RAGE: I feel you should be allowed to swap your PS2. I know you are lying to them but say that it was true, your PS2 crashes, you shouldn\'t have to have a second hand PS2 from Sony because you bought a new one from Toys R Us. Another words they have been crap over this situation. Can\'t they give you gift vouchers so you can get one when they come back in stock. I can\'t believe they haven\'t offered you anything else. I mean if you ring Sony your getting a second hand machine for your new machine you got a Christmas, its stupid! I would get back on the phone and tell em it aint your fault that they have no stock and that you would like your money back!
