I would like to get a GPS for my F3, but I don't really want to spend a lot of money for one at this time like the Garmin 590 series GPS units. I'm sure I've seen these units posted here before, but would like to know if anyone here has had any experience with these cheaper GPS units from China? Is this one of those buyer beware Items and you get what you pay for? I'm not looking to cut down any other GPS products, but as I said I'm just looking for something cheaper at the moment and If doesn't work out, it's also not a lot of money spent as well. Anyone out there with information on these units would be helpful. Thanks!
