George,
A dobsonian mount is the quickest and easiest mount to use, but is handicapped in the tracking department. It takes a lot of skill and patience to learn to track with one. It is not recommended for tracking at higher powers unless you are using a cylindrical bearing equatorial base or a Dob-Driver system. Also, the use of a wide-field eyepiece such as the Naglers or Radians are helpful because you won't have to move the scope as often. The image will have further to drift before it is out of the field of view.
All of this is expensive. The cylindrical bearing equatorial mount can be built, so that is an option.
Here are a few links;
