While I haven't felt an urge to get Dragon NS, I do have a couple of other products from the maker so I get frequent ads for discounts.
(Nuance advertising is almost as annoying as HP's.)
I believe the current "list price" is $199.99 (US) but recent offers at $99.99 have been coming in. This suggests that searching for "specials" at the Nuance site, or discounts at other vendors may be quite worthwhile; although I haven't looked at what's advertised at searchable sellers.
