The Hennessy Expedition Asym is only $129 on Amazon right now. It gets better overall reviews just about everywhere.
Although, on the Hennessy website, they have a deal right now where you get the Exepedition Asym, TWO snakeskins, and a Cub Zip (a camping hammock for kids, or short people less than 120 pounds) for about $165 ($150 + shipping).
