I'm going to have to disagree with you here Tyler. I'm aware of several ScanStations that are owned by small companies or operators that do their own thing and do not advertise that they even have them. Some of them are used by companies that do low-cost home movie transfers. But don't be fooled, the quality varies on those machines a lot depending on which model it is, what options it has, and how it's operated.
As far as Archival scanning goes, I'd agree with you that many of the larger vendors do that work - however it's important to point out they have this much more available to them now, whereas they didn't have it available a decade ago due to the costs.
