Nice finds! I had an Elite like that one years ago and gave it to a niece when she moved into her first apartment. I have a Lux 2100 as well. They're quite powerful, and the powernozzles show up on ebay frequently. I'm sure you'll be able to get one. I think you'll be very happy with how it performs. The Dirtdevil is sweet, and I have one of those too! For a cheap little vacuum, I'm surprised at what a good job they do.
