Welcome slice, 12" dob sure is a nice piece of equipment and affordable equipment without going to extremes.
I am sure the 8" and 10" offer very good views.
and I suppose that portability is another thing to be considered.
Can't complain about my 12" dob and I am sure that if you know where to aim it at, you would be extremely pleased. (Have telrad which makes it even easier).
Have 7 grandkids ages from 4 - 11, all love to look through it, once you aim it for them. The older two kids can relatively easy find planets, once you show them where to look.
My opinion 12" at todays prices is the way to go, particulalry if you have had previous experience and am on a limited budget.
Good ep's will obviously enhance the viewing.
Welcome
