I've tried to keep out of this but....
Things we know:
Dave has not made good decisions about pre-orders and time estimates
the most disturbing to me is the latest lack of communication
But we also know
Dave is an asset to the comunity and builds fantastic products
The guy is doing this as a hobby (yes he wants to break even or make a little profit)
He is not a thief (he has been in business for 5 years and I have not herd of one person not eventually getting the product or a refund)
Everyone will eventually get there yoke or there money
having done a couple little thing like this I know I am much more concerned with making the product perfect, and am not so good at the "Business" end of things, So I think I have a little more patience with Dave than most
Having said all that I'm not ordering mine till all the pre-orders are filled
