I've got an older JDS (think it is a 2000?) cyclone and I'd happily recommend them. Thing is build like a tank. I ran 6" S&D PVC pipe all over and I'm happy with the separation. Bin is a bit small and emptying it is fun if you don't want to breathe in all the stuff you have tried to avoid all at once. I put on a mask and do it in an exterior outside stairwell.
