I wonder how many people are put off by the long lead time?
It was a factor when I was looking to buy TBH - not the only one of course but one of a few that swayed me towards a similar alternative that took 18days. That said a long waiting list / backlog is perhaps a good sign and probably just as frustrating for supplier.
I got mine in less than 24 hours, I phoned the exact time Steve was informed of a cancelled order.
I agree 7 weeks is too long, though suspect something is causing that time period at the moment, it's usually less than that.
I knew a guy that built camping and boat trailers, very good one's, way above the normal quality and they were always in demand, he had very long waiting lists, he refused to take on some extra help, buy better machinery or larger premises, he stated he was happy and earning a good wage and did not want the additional pressure expansion would bring with it, he knew he was losing lot's of sales but still had more than enough for the business to survive and it did until he retired.
Perhaps they are the same, being perfectly happy with the smaller number of sales they end up with, even after many potential customers turn away at the wait time.
