What is the best MOD chip for PS2?

[Bookie]

I want it to get by DNAS , being able to use it with HDD, and to play backup copies of games for ps2

DMS3 is a real good modchip for all these needs, it's flash upgradable too. Like the HDD feature it wasn't in hte early versions of DMS3 now thanks to flash upgrade people didn't have to change to a new modchip to get it to work.
