I totally agree with you there about having to wait for the console to be chipped but if you have some soldering experience then you should be able to do it yourself in about 20 minutes, if you follow the chipping instructions on the sites. It isn't that hard i have only limited soldering experience and i have done about 5 now for me and my mates.

Most chips now for the ps-1 are either stealth or normal depending on how you wire the chip to your console (for stealth it is only 3 more wires). The stealth option with stop the console detecting the mod chip.
