I've been using a KT-A16 lately, which is a new radio that only costs about $80. I seems to work pretty well, at least tested ground-to-air, listing to an AWOS, etc. There are some inexpensive accessories available for it like headset adapters, higher gain antennas, computer interface cables, etc. Pick and chose the accessories carefully though, as there is also some misinformation regarding part numbers for these out there. The audio quality is sort of so-so, but acceptable. I also lost my PJ2! -- so I can't do a side-by-side test between them on the audio quality. I did notice that higher-end aircraft certainly come in more clearly, so maybe it's more than just the radio I'm using. The KT-A16 is certainly acceptable as an emergency backup radio in a tight spot. The brief manual it comes with though is mostly useless, but there are a few Youtube videos that delve into its capabilities very nicely, and its capabilities are fairly good actually. It's also light and compact, and seems pretty well-made.
