I could never find a price! But it is so nice, I figured even $200 would be reasonable.
So far my GPS is holding up fine, LCD-wise. Vibration-wise, too! I just wish I could leave it on the bike when running errands, but I am afraid one of these days it won't be there when I come out from the store.
I don't see the heat and light intensity that you do, either, Bob.
