Best modchip for Slim PS2

[Ryus]

Can someone please tell me what is the best modchip for the slim PS2?

I currently have a V5 or 7 PS2 with a Magic3 modchip. There are certain backuped games I cant paly like True Crime:Streets of LA.

Does anyone know what I'm talking about by some games dont play?

Anyways, thanks in advance!

Either DMS4 Pro or Crystal, IMHO.

The DMS4 Pro has more features.

Has anyone had experience with the Chipmod H2O?

This works with the slim ps2.
