Might want to wait for the DriveKey and the Wasabi DX to fully be released. They require NO soldering. They are small chips that get hooked IN LINE (via the ribbon cable) between the DVD drive and the Wii board.
Pop it open, pull the cable, connect in the chip and included cable, and bam, ready to roll.
www.drivekey.com will let you look at it, and there are a few places that'll be offering them soon.
I know there was a production hiccup on the DriveKey (should have been released 2 weeks ago), but they should be ready to go in 2 weeks now.
Thats what I'M looking forward to
