My Pentaxs aren't the premiums. I think they were around the $250-300 mark when new. And they are a big bulky unit. They actually knocked a windshield out of my pickup once. They were sitting on my dash going down a washboard gravel road and got wedged in between the windhshield and my dash and shattered my whole windshield out. Thats when they got demoted to house use only.
