Heavier telescopes stress the mount, and this is particularly true with equatorial mounts. A keen advantage of dobsonian mounts is their inherent stability. Stability is of utmost importance when astrophotograhy is being attempted. If you do want to take pictures, either with cameras or CCDs and make long exposures, then prepare to spend a large amount of money for a sturdy stable mount. Some people like small telescopes that they can keep near the door and just grab and run outside for awhile when the mood strikes them to stargaze.
Some people have a variety of scopes to fit different needs.
But if you have just one telescope and you like to use it often, make sure the process of carrying it outside and setting it up won't hinder you from using the telescope. Look in the sky and find what you want to view, then target it with your finder, such as a Telrad and get the target in position. Then view through the eyepiece. Then you nudge the scope along to track. Equatorial telescopes can be crudely pushed and pulled into position, but if they are polar aligned you can use the manual setting circles to position your scope to get into the general area of where you are supposed to look.
