Q: Should I buy a used wii console? That's all I can afford, but I don't know the shelf life, don't want to get stuck with any problems.
A: I agree, it's not worth saving a few dollars to get a used wii console. It's better to get a new one with warranty for $250. You can try to find some deals from http://www.gamez4sale.com/Nintendo_Wii_Console
