Same boat (or tank ) here "unforeseen delays" I was told then e-mail went quiet since then. That was last thursday. Order went in 8/5.
I have even tried to work with him to get one of a couple models if in stock since I had a hard time choosing just what I wanted.
Hmmmmmm......
You never know what someone may be going through in their life, business etc... but not to be cold here, his problems should not be the customers problem.
Shut it down if you can't handle it or regroup and come back when you can please the customer. He's doing bad business here.
