Help Choosing Modchip!!!!

[dansanch]

I have a PS2 NTSC 30001 V3 system. I want to buy a modchip and I don't know which one to pick. So far, I have found the following ones:

Origa
Novachip
Neo 4.1 no swap

Also, I have been told that messiah would not work with my system, but in the following webpage it says that it works. Does anybody knows if is true? The webpage is:
http://www.elitemodchips.com/messiah

Please guys, help me find the best modchip for my system.

Thanks.

Daniel
