Depending on how much you want to spend will depend on alot , you can get a Garmin Etrex or Ghecko for $100 anywhere. They have 10 waypoints that can be saved if memory id right , also are very small and fit in your shirt pocket. I use a Garmin GPS72 which is a bit bigger and has alot more features, It sells around $150+ . The latest is the GPS 76 I believe and is about the same as the GPS 72. If you want the basics , waypoints , compass and travel then the Etrex and Ghecko are hard to beat. I have owned the Etrex and is a great unit for the money, you can get them on ebay for about $80 or so , they also hook to a laptop with an extra cable aswell. The garmin website has about all the info you could need. IMHO stay with a name , Garmin is one of the best and their prices are hard to beat. I have owned a few different ones and have always been happy with Garmin , if you have an Academy close , they usually have about 10 different models on display ,BassPro or any major outfitter should also have a GPS section as well . Once you pick one out and make your purchase , play with it around the house and such and find out what your battery life is. It bites to go out and have battery failure in the middle of a stand or after dark when you cant find your truck.
