I have one as well, if you look under Aerus, you can do a dealer search by zip code to find a dealer close to you. I bought one of the first, and I know they made a few changes since then, like making the machine shut off when the bag needs changed. Mine just turns on a light to tell you when to change the different filters. They also came up with better style P bags, made out of hepa material. While you are in the Aerus website, you can go to their store and check out the prices of bags, hepa filters, etc.
I don't know the current price, but it all depends on if you have a trade in etc. I bought mine 3 or 4 years ago. I didn't have a trade in.
