I have a softmodded wii (wii modded without any modchips), and it's hell whenever a new firmware update appears.

Best to buy ori, stay ori with the Wii. Quite worth it, I never regret any of my original buys for my Wii

Be sure to get at least another extra set of Wiimote + Nunchuck.
And get Wii Sports Resort. Buy the one that comes with MotionPlus, and get an additional MotionPlus if you are getting an extra remote.

Even with Wii Sports and Resort, will last you a long long time in great gameplay
