I got the Garmin Deluxe V from best buy for about $150.00 and a tank mount from from a froogle search for about $14.00 I absolutely love it. I just wish the screen was in color and a bit bigger, but hey for $150.00 compared to the $700.00 models I can't complain. The thing that really sealed the deal for me was it is water proof and you can use it as a handheld if you do a lot of hiking like I like to do or even trail riding. I haven't had any problems with it except that one of the streets near my house comes up as a different name as I am passing by it. Another nice feature on it that I like is you can find gas stations, business, restaurants, hotels, government buildings and just about anything you can find in the yellow pages on it and it will plot it all out for you on the go. Hope that helps you out.
