Mojo UFO, 1 lb, 11 oz - $1,799.95
Hi-Tec V-Lite, 1 lb 10 oz. - $26.95 (That's what I paid, but that was on sale)
For those who are truly obsessed with ultralight gear, space-age materials, and mass produced designs, I offer the Hi-Tec V-Lite. Made with the insanely light and virtually indestructible polyester and nylon, the V-Lite weighs a scant 1 lb, 10 oz and will stand up to just about anything you can dish out. Rolls up into a unique, ultralight nylon stuff sack instead of an envelope.
I used it on the JMT last year, and because its slightly used I'd be willing to part with it for $1699.95, a full hundred less than I would otherwise ask but the Tyvek groundsheet pictured will not be included. If you are truly obsessed with ultralight gear, you will Paypal me the money and I will ship it off by tomorrow. Shipping is free.
