Hey Mudge,
My Dad bought a Motorola, I forget what version, but it works really well, it has quite a few bells and whistles that I don't seem to use. He got it for the purpose of listening to the frequencies at airshows, but then it found its wayinto my flight bag during my flight training as a back-up radio if ever needed in flight, or in the event of a forced landing on a long cross country flight.
It sure is handy. The one he got was very tiny. The body of it is smaller than the palm of your hand, and the antenna is about 8 inches long. I think it came with a belt clip too. I can't remember exactly, but it's a good little thing. It put him back a bit. They are quite pricey.
I hope that helps.... then again, reading over it, probably it probably won't.
here's Motorola's list of products. I hope the URL works:

Cheers and happy/safe flying,
David
P.S. A good way of convincing Mrs. Mudge to let you get one would be to say that you're getting it for safety reasons when flying, like I used mine for... or luckily, never needed to use mine for.
