I have and Ameristep Doghouse. There's not as much room as the same size Double Bull because of the round top. But It works well. And cost $70.00 compared to $400.00. I never used it to much deer hunting but we used it for Turks, and it worked great! Go to www.ameristep.com I don't have the TSC and I'm not sure it's worth the extra money. Check them out for yourself. Also the Doghouse is really easy to set up and take down. You basically just throw it and it pops up.
