If this fellow is so far behind, why is he allowing more orders? I think telling people not to order is not where the responsibility lies. It lies with the vendor. If he is truly behind, and swamped with orders, it should be his responsibility to put a hold on new orders, until he can get himself caught up, and re-evaluate his stock. My concern is the (way) future orders he is allowing to be placed via his web site. I am sure he's a nice fellow, and means well, but much can happen in this very lengthy time frame to prevent him from being able to fulfill all those future orders, thus necessitating a whole lot of refunds. Which may or may not happen.
I would say with this vendor, Caveat Emptor, and not based on anything personal, but more based on his sales methodology.
For those who have placed orders, I would address any concerns you might have directly with this vendor. And for those who might be tempted to place an order, I would say, be willing to spend money, and possibly not receive product, if this person is that buried in orders, yet has not put a hold on additional new orders.
