Wayne,
I looked at a Jet DC and thought..."just buy it and stuff around with the cyclone later". So, in a moment of weakness, I did just that. It sucks like a beauty, and in light of my saw purchase it was an immediate necessity, because I think I will be making quite a bit of sawdust in the next couple of weeks.
I have also finished the dust collection part of my mitre saw unit, and it was crying out for some suction too. Pic attached.
