GPS question

[billhurley]

I know the question has come up before, but I was wondering is it possible to get an inexpensive good GPS that uses the Bizer information. I have never used GPS, but every time I come back to the marina from a night trip I get the question did you use a GPS. I am not sure if I really need it, but wonder what kind of investment I would need to make to get a useful one.

Thanks in advance
Bill
