My guess that people got good service from this company a few years ago. For some reason or another, say magazine article or some other marketing, demand is up for the tanks and he can no longer keep up with demand. This happens all the time to small shops with a good product and not so good business sense. People have stated on this thread that they got excellent service and a fast turn around. Well, a six month wait for a non-custom part is not reasonable. I emailed the company a while back after a friend ran into the same 6 month delay issue and never heard back from them. It looks to me like they will solve their own demand problems by losing valuable customers.
