Sierra Designs Tensegrity 2 Elite
$360 with free shipping to the continental US. Paypal accepted.
Used 8 nights. There is some dirt on the floor (inside and out), but otherwise it's reasonably clean. I made a small repair to one of the trekking pole pockets (see third image), and there is a tiny hole in the stuff sack from abrasion while strapped to my pack.

I seam sealed it with a somewhat thick layer of SilNet, but it doesn't add much weight.

Includes tent, pole, nine DAC stakes, and stuff sacks. Trekking poles at least 120cm long are required to set it up. It works with fized length poles. Straight poles are available from Sierra Designs if you don't use trekking poles.

Note: Trekking poles, red footprint, and red "Y" stakes not included (those belong to my other tent)
