Harley,
I found the DS80 in a weird junk shop. It was $15. When I turned it on a BUNCH of dirt blew out as the emptor tray wasn't properly seated. It was in good shape. When I went back it was gone.
My instinct was to pick it right up, but I have two Royals I hardly ever use. I also have no more room for more acquisitions, really. Sometimes I feel I did the right thing by passing on it, but then I'll flip flop.
Apart from the emptor and the removable nozzle, I'm getting the impression both offer similar performance. I know, I should have bought it!
Any other opinions strongly preferring one over the other?
