I think that the Ameristep Doghouse and Doghouse TSC are two excellent blinds in terms of overall size, portability and design. The standard Doghouse is big enough for most folks to use in just about any application. Some longer draw length archers complain of it being slightly cramped so the 8 inch wider TSC model might be the better option in such a case.

Price is the best part....around $70 for the Doghouse and $120 or so for the TSC model most places.
