I am looking to buy a GPS with plotter. I do my boating on lake erie around the islands. My range is in the $400 area. Any one have any suggestions of what to buy if they have one.... what you, do or do not like about what you currently are using....do I go with a handheld or fixed mount?<br /><br />There are just so many choices that I would appreciate someone with experience.<br /><br />Thanks a lot! Merry Christmas!
