Or, as a totally different tack, you could look at a small fast refractor on an EQ mount (A HEQ5 would do) and a mallincam type setup.
You get 'live' views of many DSO objects, and many with full colour, in many ways in greater detail than you get through the eyepiece of even a huge scope.
It is easy to transport around too, and allows for basic photography as well.
Check out the Night Skies Network for more details of 'video astronomy' for DSO lovers it can be a revelation.
