I got a x100c a few weeks ago from Cabela's at a discount because it's last years model. It was replaced by the x102c and is at a sale price because of that. You can compare them at Lowrance web site, but the main difference is the pixel count. However I do also have a LMS480 on my console so this is mainly for the front or if I have trouble with the 480 I can put it on the console, but it does not have the GPS like the 480. Here is a link if you are interested and I got the $379 unit.
