Hi cj.
&
You will not go wrong if you remember the #1 'Golden Rule'. That is 'Aperture wins'.
Starting out with at least a 10" f4.5/5 dob would be my suggestion.
The tubes are relatively short in length, easily transportable in small cars, will give great views, are easy to keep in collimation & assist with you learning the night sky.
They can be modified to do 'almost' the same as most driven t'scopes.
The FIRST thing that I would do tho, is get myself to a club meeting night/observing night to 'SEE' what is avail.
There are just too many options.......... but do not skimp on eye pieces or barlow lens.
HTH.
