Don't want to hijack this further, but this is an ongoing problem and I mean no harm to the OP (I know he didn't intend to get into any of this). Maybe this is a good opportunity for you guys to get together and have a video made testing/comparing Ken's products to the others and have a frank, open, honest discussion of the issue with knockoffs. I can tell you first hand his stuff is beautiful quality all the way through and will be easily appreciated by folks like us. Even with my glasses off the difference in quality of welds is immediately apparent!
Ken, do you have any sort of trademark or copyright protection on your products? (Patents are good too, but the cost to enforce them makes it all but impractical). I had one of my products knocked off by an offshore company, and what finally got them was that they had copied, verbatim, a lot of information from my owner's manual. The manual had a copyright notice on it just out of habit, but in the end it was what bit them. The violation was easy to prove and document. Trademarks are similarly helpful.
They way I look at it, if someone wants to take the time to do original work, it's a fair market and they have the right to compete like everyone else. But once they start copying designs, engineering, product names, user manuals, etc, it crosses over to laziness and/or blatant efforts at a ripoff. They know what they are doing is wrong, and hopefully the original business has the protections in place, and budget, to stop the practice.
Finally, in some cases it's difficult/impossible to go after the company doing the knockoff, but resellers are more responsible and responsive. Amazon will pull products/vendors if copyright/trademark/patent violations can be proven.
Again, no harm intended in my post and I hope the two of you see an opportunity here that is mutually beneficial.
