I've been running with gba and DS carts for a while and am rather pleased at the amount of time and money saved being able to demo shovel ware via download. I see right now I can get a Wiikey off EurAsia for only twenty bucks, which is a hell of a lot less than what I paid for my last DS cart. The question is, is it worth it? I've heard little bits about new chips coming out, and while I do have some soldering experience from college classes; I don't want to brick my Wii. Recommendations from the more experienced, please?
