I havent bought a ps2 yet but i am about to.
Which modchip would be best to use? I was looking at the No solder one but i dont know if ill get a V5 or not and ive heard the messiah is having dvd problems. Can anyone give me some advice?.

Theres about 4 million topics exactly like this one. Get the Messiah, the problems playing dvds are due to a faulty installation or a bad laser, if you get someone good to install it youre not gonna have a problem. End of story.

Mod chips for sale/wanted & anything remotely related to that.

Also, if you need it, there is a search engine (You can't search for anything that is three letters or less):
