I recently purchased a tarptent from Antigravitygear and had a chance to set it up this weekend. The setup was pretty easy, had plenty of room inside for me and my pack plus the weight came in at 22.9 ounces. Looks like hiking in Texas just became a bit lighter for me.....
Here's some photos if anyone is interested....
