Well now with the introduction of rockband 2 for nintendo wii, you can also get a wireless drum set for rock band on the wii. A wii wireless drum set is identical to the original rock band drum set for your wii, other than being wireless. A wireless drum set allows you to take the drum kit and set it up anywhere you want without being stuck attached to the wii console. A brand new rock band wii wireless drum set can be found for anywhere between 30 dollars up to 70 dollars, so make sure you research the wii seller and look at shipping options as well. Used rock band wii wireless drum sets can be found sometimes for as little as ten dollars, however, a used set may give you troubles as you do not know what kind of abuse it has been tyhrough. I suggest a new set, you're already spending the money, may as well go new. It's not worth the hassle to buy used if the wii wireless drums are just going to fail out on you.
