Having operated an authorized Rainbow service center for almost 25 years, before the Vacuum Museum, I sure wish we had the Sirena then. All the D3 and D4 repairs we did, I could have flipped a good 1/4 into a new machine. Now that the parts for D3 and most D4's are obsolete, what a wonderful machine to have for sale. A new motor for a D3 or D4 machine would have cost the consumer at least $400 plus labor, not to mention the rest of the old machine was old too. For $800 with a trade-in Rainbow, a new Sirena would be the way to go.
