I've got the Garmin III Pilot. I love it, and would definitely recommend it. Its nice and small, and its got everything you need- runways, freqs., airspace, moving map, etc. The backlighting also works really well (but if you're going to use it a lot at night, get a cig. lighter adapter). You can also download software and database updates right off Garmin's website, which is nice- no waiting for chips or disks. With the exception of com/nav and approach capability, it can do anything a Garmin 430 can. Mine is mainly a backup now, but our three primary trainers don't have GPS, so I use it quite a bit in them.
