Whistler Golf Digest GLF-125, works well enough, hasn't really led me astray yet. It was only like 35 dollars and I got 5 courses free, I only ever really play 2 different places but have used it on 3.
How many of you use GPS on the course? - Page 2

Garmin Approach G5 (the earlier model of the G6), and it's the best I've seen. I've used two different lasers and 2 different GPS receivers, and been with guys who used just about everything out there, and I prefer mine to anything I've seen. Fast, accurate, 30,000 course data base and no subscriptions, great features.
Some don't like it because it uses two AA batteries instead of recharging, but I bought it because it doesn't need a charger. With a charger, I either have a dead unit in my bag because I forgot to charge it, or I have a fully charged unit still plugged in at home when I get to the course. With AA lithium batteries, I keep 4 fresh ones in the bag, and I get about 7 rounds per pair, so that's not much of a cost to always have the unit ready to go. If I do forget to put new batteries in the bag, I can pick them up anywhere.

Been using the Bushnell Neo for 6 months now and i like it. Don't wear it on my wrist though. Either i strap it onto my push cart handle or i hang it off my bag if i'm in a cart. Going to try starting to wear it on my right hand to see if that works. Its the watch/glove thing that bothers me with my left hand. Btu overall the GPS is nice. Front, MId and back of greens and hazards is about 90% of what i need to get through a course. A rare blind landing area on a course you never played before and the watch is pretty much useless.
