So here lies the question, knowing that a short cyclone doesn't work as well compared to a longer one, why no pony up the extra money and get something that works like it should without having to monkey with it to make it work. Other list height being the deciding factor, you say you don't have that problem. Also you list you have bought some very nice machines, so why not buy a nice dust collector that works, sure they aren't sexy like a table saw or 15" planer, but make a big difference in how you work overall. The time enjoyed working in your shop rather than having to deal with a piece that causes problems is worth the money to me anyway.
