John, as I mentioned in your other thread, short-cone cyclones inherently don't separate as well as larger, long-cone cyclones. It's the nature of the beast; IE, the laws of physics. What you might consider instead of the units you mention is to use a rolling "traditional" DC with upgraded bags as your temporary solution and when you're ready for duct work, acquire a more capable cyclone system that you can isolate in your shop (for sound) and pipe it in. By then, you'll also have a better handle on what tools you need to support with your DC so you can optimize what you invest in. I personally wouldn't buy a short-cone cyclone because the separation is "everything" and one of the primary reasons for having a cyclone system.
