The USB Roll Up Drum Kit has 6 pads for you to play around with, and software that will teach you how to drum along to your favorite songs at whatever tempo you want. $40
Oh! This is so fun! Why haven't I seen these USB instruments sooner! Record music and play the drums without the whole...drum set hassle thing. It rolls up for easy storage. So fun for kids and adults alike. Great gift, but I think I'll pick it up to discover my own drum talent.
How fun! Seems like a good "instrument" for apartment living, since it can be easily rolled up and put away after you're done rockin and rollin.
