Dan, did you go with the paper filter or the fiber filter?
Al, actually neither at this point. Since I already had the Delta 50-720 DC I just used it on the outlet of the separator drum. This gives me the pre-separation of the Thien baffle in the drum and the 1 micron bag on the Delta.
I think it is "closer" to 2HP than the older model and has a little bigger impeller. IMO if you buy it at the sale price of ~ $140 you are paying for the motor with is the part that is worth something. The rest of the machine is really just a few bucks worth of sheet metal and some plastic bags.

All in all though IMO it's worth the $140 and can be a decent DC if tweaked a bit.
If I were going to use the HF DC "as designed" I would go with the fiber filter. Even though it's .5 micron larger than the paper filter it's rated better at handling fibers but the big thing to me is it's washable. So when you need to really clean it you can wash it, dry it out and your almost like new again.
BTW I've added a few pics to show what I've done with the two DC's. The drum is about 1/2 full and you can see there is barely anything in the bag at this point. I was going to just run the outlet of the drum outside but figured I had the other DC so I might as well use it.
Also, not trying to hijack the thread with the pics etc.
