I wonder if something like this might suit you:

You won't get the high megapixel images from it, but I wonder if it would be the ideal combination of ease of use and image quality for you?
I have not seen the GStarEX in person. I have seen the AstroVid Stellar Cam which I believe is very similar, and I was impressed how with it plugged in to a portable dvd player you could easily see nice images of globula clusters, planets, moon.
I think these camera's work by stacking frames internally, as specified by you through their menu system. You then end up with stacked images coming to the video screen.
As I say, I haven't used one, but do think it might be a good option for you.
