I was going to get the 1000 or 3000 series, but when I started looking on eBay I saw this listing.

It seems more similar with the 8000 series. I believe this is the dentist version and not retail, but seems to have almost everything retail should have other than the price tag. I ordered one, so we’ll see how it goes.
