I owned a Hex for a short time. It's not a bad shelter, but as others have pointed out it's difficult to ventilate. It's particularly difficult in the rain. Because of the pyramid shape any amount that you leave the door open is the amount that the rain will come in.

I now use an Alps Vertex 4 (for family backpacking). It weighs a little under 8 pounds (slightly modified) but easily sleeps 4, it's free standing, and great in all weather conditions. Plus they can be had for about $175. I've had mine in wind, rain, and snow, in heat and cold - it performed well under all conditions.
