Dave,

looks like you are right about Protool. They must have changed the name in the last few years. Now they are offering their handheld tools under the Protool banner and are using the HolzHer brand for their CNC machinery.
The Protool saws and mortisers look exactly like the Holzher used to.
Having used both, HolzHer/Protool and Mafell I prefer Mafell. I did like the Holzher Beam saw though. But again the Mafell is easier to adjust. Pricing is about the same for both.

I still would like to see a chisel mortiser and know its advantages if there are any. Same for the Makita chain mortiser.
