What Chip To Get

[Renegade_Playa]

Hey guys

as you can see in my sig i have a v7 PS2...but i'm thinking of getting a new one

I'm planning on getting either a V9 or V10 PS2 (need to play off the HDD) but the main thing is that i don't know what chip to get as it's been a long time since i've gone out and chipped a ps2

My choices are
DUO or DUO2 (I have a DUO currently in my PS2)
Matrix Infinity (If I can find it here in Australia - can somebody tell me where to find it here in Australia)
MODBO 745 (My friend just got his PS2 chipped with this - and the gameshop near my work install these chips)
DMS3+

what do you think of the chips mentioned above and which one would be the best chip

thanks in advance
