If you're more concerned with space (big) and price (small) than anything else, get the Zeta 3. There's no cutting corners on interior dimensions: One tester squeezed a family of four into the 43-square-foot Zeta and reported no fights. Two vestibules–one a cavernous 18.5 square feet–store gear away from the doors.
Puzzling together the hubbed-pole structure takes a practice run, and it's a tad heavy, but the extra ounces are justified by the extra space. Biggest drawback: Despite large mesh panels on the tent body and a vent on the fly, condensation accumulated in humid conditions, and the sides lack enough guy loops to keep the fly from flapping in the wind. $249; 6 lbs. 9 oz.
