I have a UV-82, programming it with CHIRP is a piece of cake so long as you get the right driver for the programming cable installed. I just got my technician last fall and have been playing around with it a little bit, not a lot of activity in my area. I may try to get my general license here this spring/summer just for fun and to have access to the other bands. In the truck the UV-82 works ok with a nagoya 771 antenna. If I get a dedicated rig (and decide to spend the $$) for the 4R it will be a kenwood D710G so I can play around with APRS. For a basic dual band rig in the truck the yaesu radios seem to be pretty solid (like the 2900 stated above).
