Len,
Until we actually start cutting the fabric of I won't have an ETA. I hope to know more next week when my mfg. gets back from vacation. As to pricing it's still a bit up in the air. I expect it to fall in between $400 & $500. While that may seem to be a steep price, we can only keep it that low by not offering it through the retail chanel and it's higher margins.
I've not done a Cuben Fiber version of the Lunar Solo and don't have any plans. I did do a Wild Oasis version and it's final weight was 7 ounces. That also included some ultralight mesh that isn't No-See-Um proof. I'm not sure I'd go that route on a commerical version.
