I'd like a body, but have a few comments (not snide!)...
It seems like the 2xAA body would be a dandy battery carrier, if only there were caps for each end... or even a spare Kings Crown™/switch assembly to facilitate faster change-out. Barring the second switch assembly, some sort of threaded cap would be nice since the body tube is as safe as place as any to store AAs.
I imagine that a second switch assembly is a signifigant cost (and one of thousands of "design-by-committee" suggestions seen daily on this board), so perhaps I could buy that seperately?
