If you can come to Lostock with us this month, Pete, you will see a variety of different DOBs, some with goto others, push to, and others fully manual navigation systems.
Also different sizes from 8, 10, 12, 14, and 16 inch versions (mostly collapsible and truss designs, from Skywatcher, Orion, Bintel, GSO and Meade.
There will also be a Meade SCT.
and possibly a refractor or two.
You can compare views and the owners' experiences.
The Skywatcher and Orion have Pyrex, I believe, which is generally considered better material for mirrors, The others BK7 glass, whioch is also used in most binos.
Hope to see you there.
