FileForums - Neoriga? and my v5 ps2

Hi guys I'm trying to figure out if the ps2 I plan on getting next month, which will of course be a V5, will work with the neoriga combo? Now i went to origa's site and it said that V5s had not been tested. But I went to an intaller's site and he said that the origa 1.0 would work in my machine. Now who is right? Secondly, will either the neo4 or neo4.1 work in a V5? I'm pretty sure the answer is going to be no, unfortunately, but i still want to know for sure. Also what's the difference between the neo4 and 4.1?
I currently have a V2 with a usb mod inside but I want to upgrade so i can get a complete no swap method and I understand that the V5s have better dvd drivers, better lasers, and I'd like to give my old system away.
Thanks for all your help and insight. It's greatly appreciated.
