I just bought the Double Bull. Very pricey but will be worth it. I hunted out of a friends and it has to be the best on the market.

I have a Ameristep doghouse that I will get rid of if you are interested. It was only used once. The only thing wrong with it is that one of the ground anchors pulled through when I put the anchor pins in it. Can be resewn, just haven't messed with it. PM me if you are interested in buying.
