I use a Garmin Etrex Legend ($200.)Garmin's website. It comes with 8m of memory to upload maps. The maps are pretty big so if you can afford more, the Vista comes with 24m and runs about $300. It will loose signal sometimes in thick tree coverage but only for a few seconds. I have used it many times to make maps of the trails I like to run. Its nice not to get lost anymore. I always know where I am going now.
Here are a couple of sites with good info:
