It seems there's a lot of new focuser motors available at present or about to come out.
There's the WO one shown in another thread:

Apparently ZWO are also about to release one.
I came across this new one:

And this upcoming offering from Primaluce Lab looks very impressive as an all-in-one motorised focuser a bit like Optec designs:

Plus they have their Sesto Senso motor released in the last year or so:

Lots of competition for Starizona, Pegasus, USB_Focus, JMI etc
