Huh, that's very cool! Those things are usually expensive... and yeah. that the batteries are external is very strange. Apparently the battery boxes are harder to find than the systems are... but as for keeping it, other than using it as a wired handheld at home... well, it'll use up 6 AAs in just a couple of hours. Expensive, or time-consuming (with rechargeables, given the amount of charging time it'd take), to use. Still cool though.
