I know of a place you can buy a PAL PS2 with Messiah fitted for $413.00 US. You will need to buy a Step-Up converter since the PAL version is 220V and US is 110.... But that's only about $20.00.
Also you might consider sending your PS2 to the place Charlie Rec... They may be able to fix your PS2 for less money than to buy a new one....
The choice is yours......
