Thanks all for your comments, I'm rethinking everything.
I'm going to first start with getting the right mount. I'll be storing this in a garage with plenty of space, which is only 20m walk to the middle of my garden. So I should be able to carry a 20kg mount this distance, I'm not afraid of a little heavy lifting. Also once or twice a year I would want to show off my telescope to friends, so being able to stick it in the boot of a car would actually be a requirement.
I like the idea of the combined EQ and AltAz modes of this one;

And I might as well get the bigger one, as I assume this will be my forever mount. Do these mounts come in a nice box that folds away and can "easily" be placed in the boot of a car?
Although maybe I should be going for a lighter more portable AltAz mount for visuals and a heavier EQ for the AP later down the line.
The advantage I guess of having two mounts is I could get an AltAz one now and spend more on a couple different types of better scopes.
Maybe between these two, sky-watcher and iOptron seem to be the popular mounts?

And then later on I get the EQ/HEQ/NEQ - whichever is the heaviest and best, if/when I decide to get into AP.
Now I need to redo my research on scopes, an evening of youtube for me.
Thanks again all.
