Modchip for 9001 PSX - good place to buy from?

Hi... I would really appreciate it if anyone could tell me of a *trustworthy* place to get a stealth modchip with latest technology that definitely works for a 9001 series PSX.

I recently got one from www.mod-chip.com and after 2 weeks of troubleshooting, it finally worked for 2 hours then died! I tried emailing the site and they did not respond - frankly their customer service sucks big time. They replied quickly the first couple of times, but my last email telling them that their chip is definitely the cause of my problems was ignored.

Any help/advice would be great! Thanks

i'd go with modchip.com, they have good new chips that cant be detected by the modern mod-chip detection software in the psx cd's.. but if your looking for really good customer service, go with easybuy2000.com, you can call them up and bitch at them something does go wrong.. i'm not sure of the 'newness' of there chips tho.
