The Meade ETX is okay, but the views of DSOs will be disappointing. Yes
it makes it easy to find them, but most will look like faint smudges.
Another issue you will have with it, is the cool down. It takes about 90
minutes to reach ambient temps. So the ETX is not something you can just
grab and be observing with in a couple of minutes. Yes you can see
things immedieatly, but you will also be seeing thermal currents in the
tube which will give poor images.

You do have to move the dobs manually, but you get the most bang/buck
with them. They also have to cool down, but typically take about 30
minutes to cool.

One thing you can look at is Orion's Intellescope series. It has a push-
to system that directs you to what direction to move the scope to your
target.

I'm not familiar enough with these to answer this.

Check Cloudynights.com or scopereviews.com for good reviews of
equipment. Also check out your local astronomy club and go to one of
their meetings and Star parties. This will give you a chance to look
through a variety of scopes and talk to the owners of them to find out
their pros and cons.

Hope this helps
