Again, these chips CAN NOT brick your console. I cant stress that enough. Unless you solder a shoe instead of the actual chip to your Wii, It wont get bricked.

I say the CycloWiz is better, as its easier to solder on and you got less chances of dripping solder out of the PCB (now THAT will brick your wii.)
But really. Theres like 10 games for the Wii at the moment. Why not just buy the games? If price is a concern, wait for freeloader and buy exclusively from the US as they will have more games than poor old Australia!
