I'm going to buck your request, but bear with me for a moment. If you already own an Android phone or tablet, the Mobilinkd Bluetooth TNC is a viable solution. Yes, it isn't an all in one solution, but the TNC is barely larger than a box of matches and runs several days straight on a charge. You can easily velcro or rubber band it to your HT. At $60 bucks, it's a heck of a solution. Combined with APRSDroid, you have a FAR more capable portable APRS system that costs much less than an all-in-one APRS capable HT. Assuming you already have the phone/tablet, you could get a Baofeng UV-5R, TNC, cable and better antenna for around $100-130 USD. Don't let anyone tell you the Baofeng is a bad radio. It's kind of a pain to program, but is a solid performer and a steal at $30. Or go with whatever HT you desire. The Mobilinkd folks sell the TNC to HT control cable for various brands of rigs including Yaesu, Kenwood and Baofeng. Even if you don't have an Android phone or tablet, an old used one without a data-plan is perfectly usable for this purpose.
