Re: gpsI own an iGolf Caddie II and have used a skycaddie SG4. Some people don't like the golflogix because they don't allow any self mapping, and you have to use what they give you. They may give center of bunker, but it is 30 yards long and you want carry distance. They also might not have a point mapped that you would want mapped. You also must have a subscription every year since the unit doesn't hold courses, and you can't save them to the computer. iGolf has a model for $150, called the Neo, and I would think it is better for the price.
