Have you looked at the Fox Delta stuff? I have one of their all in one tiny box devices, that does APRS (Modem Built in) beacon and receive. All you add is a radio of some sort.

Only thing I warn you of, is that it would be FOB India, so shipping times are a little extreme. I think I waited about 3 weeks for mine to show up, but I also ordered one that had already been built. I've been very pleased with mine. Here's the link..
