I am assuming you are referring to the Magnus Pack Rack? I have one an absolutely love it. I was able to bargain with the fella at Gander Mountain and get him to price match the web for $149.99.
I have struggled with getting ground blinds back into their bag in the dark. This pack distributes the weight evenly and makes it easy, even for a cripple like me, to carry a ground blind in and out of the woods.
