I agree they are expensive but you identified a $580 MSRP vac. That's about the same price as the CT26E Festool vac which has similar performance. Plus, it's actually quiet (a major selling point) and it's made in Germany.
I've never looked at the specs for the festool vacuum because it appeared to be a limited use unit. I also don't see how it could perform any better than the Dustless, but I'll check it out.
