An Equatorial mount doesn't prevent you doing visual although it can put the eyepiece at a funny angle sometimes so if you still intend to go imaging one day it still means you need to ge the best mount you can afford at the beginning unless you are prepared to upgrade when required. That is the expensive path to take as although they are saleable you know you are going to lose each time.
Best advice, buy a biggish DOB, 8"-10", preferably second hand so it's cheaper than new. Check the classifieds here for a starter. Get your head around using it for a year or so till you are comfortable with sky navigation, and the general rules about the obsession.
THEN, when you're ready and have decided where you want to go either move the DOB onto the next beginner and buy what you need. You will recoup most of your investment in the DOB or like many you will retain it for visual use anyway and a Push-pull DOB is not that expensive these days.
I think most people will have found that is the best starting point to learn from.
