I think I would like to buy one as a back-up for not having a usable radio. It would rarely get used. AOPA has an small statement on the PJ2 that plugs into your headset at 199 dollars.
I like my Yaesu FTA-250L. It comes with an adapter for aviation headsets. It also has a Rechargeable battery, but comes with a double a tray is that is your jam.

I have a YAETSU 230 and am happy. Bought it for the size, it fit perfectly into a side pocket on my flight bag. They are up to the 270 now which fixed a couple complaints I had about the 230.
