ya thats expensive ! the geocities one is expensive , you have to buy the chip , tehn you cant load games os you have to buy the game shark to , and there sanother chip its like 280$ to install and with that you could play burned games !
The cheap one is Neo 2.2 which requires the swapping technique with the Gameshark. The 280$ one is the Neo 4 one which is very limited since the comapny that makes them was shut down. It's also extremely complicated to install it... The best one at the moment has to be the Neo 2.5 DVD-Key which you can order of the net from www.modchip.ca. The Neo 2.5 DVD-Key is the only one along with the Neo 4 that can play DVD Roms but to use the 2.5 you need to have a version 4 system (Serial starts with 4-8, or sumthing like that). Im waiting until the Neo 4 goes down in price cause it's the best.
