Yes I would. I know someone makes an aftermarket AA body adapter for the AAA head, but I wish ARC would make one.
I'm really big on "battery diversity" because I'm concerned about earthquakes and possible terrorist attacks on our power grid. I have a lot of AA's in my remote controls, anwering machine, Maglites, stereo equipment, label maker, photo slide viewer, handheld fan, electric shaver, closet light, and other gadgets, which I could tap into in an emergency. Although the AAA battery is becoming common, there are some small stores that don't carry them.
It would take so little for ARC to manufacture an AA body adapter. I don't understand why Peter relinquishes this market segment to CMG, unless he has an agreement with them to stay out of each others market.
