There is a big difference between the Clague, Hugget, and Donny Fl moderators...I currently have three Huggetts and one DonnyFL Sumo, and I was unfortunate enough to have purchased a Clague in the distant past. Of the three, the DonnyFl is the quietest, but the Huggetts are almost as quiet. Both the DonnyFL and the Huggetts are designed and machined perfectly. I like the looks of my Sumo, but I also like the looks of my Huggetts with the smaller diameter profile and rear vents. Both are really amazing and may be completely disassembled for cleaning.
Regarding the Clague? They are glued together with two part epoxy and can only be disassembled by heating them with a torch until it releases, and then when you see what is inside you will laugh! I think they are a poor substitute that cost about as much as the really good ones do. If you have a problem with it he will not allow you to return it for a refund claiming that his website clearly states that "Because each LDC/shroud is custom made to order, I do not offer refunds/cancellations on orders once payment has been made."
