What Modchip should I get for my ps2

[Renegade_Playa]

I was wonder if anyone can help me
I got a 30002 model PS2 and i dunno what chip to get..here in australia we can get magic 3.0 and 3.5 (i know it's a clone) or messiah 2...which one is best for me

and Is it true there was a faulty batch of messiah 2's that came to australia and also i heard from some installer that the magic mod chips will stop spining if the game stalls and the messiah chip will keep spinning...is that true

Your help would really be thankful
