Modding one of the Wii Hori stick is almost the same as modding that PS2/3 stick you had. The PCB is easier to solder, but that's about the only difference. I think the TvC sticks are kin to the SE sticks. Another option would be to get your stick modded with a PiiWee and extension cord to attach it to your wii-mote. Much cheaper than getting a whole new stick/modding a crappy one at least.
The more you know.
Saturday morning/afternoon is busy, but I'll see about coming down. Don't expect much after that till break.
