The Doghouse advertised for $69.99 in the Sportsmansguide is the 2003 standard model. The TSC model of the Doghouse is approximately $30-$40 more at most places. For the extra money you get the scent protecting memberane built into the shoot through netting on the windows as well as gear pockets built into the blind, a zip out floor and 8 inches more width to the blind (60 vs. 68 inches).

I am struggling with the decision of picking up which one myself. I had no problem drawing and shooting out of the standard Doghouse when I owned it but I like the added features on the new TSC model.
