bighammer,
Do you recall which model it was? Just bought a Garmin GPS V for my wife, since she is going to visit my daughter in Illinois and will be renting a car. I was going to buy the Street Pilot III, but Garmin does not have a Hawaii map for it yet, but the V does. Seems like the V is a better buy when you look at the cost of DCA's for it and the extra features it has over the SPIII. It is also only half the price. Cons are no color, voice prompts and smaller display, but still way better than looking at a paper map!
