I actually just bought a Purple Dirt Devil Can Vac at a thrift store yesterday for 7 dollars and it's awesome! Mine has the powernozzle though, and mine also came with the original box too!
I had a lady come into the store yesterday needing a hose for one of those. She said she will never buy a new one, she loves it so much. She said she loved her PowerTank even more, but her daughter took it when she moved out.
