For colour I like the ASI224MC with an ADC and for mono I like the ASI290MM.
I have both but haven't had a good night with the ASI290 yet. I find it more fun using the colour camera and you can get some really good results with it!
I use my DIY 20" goto dob.
Here's a link to my flickr page. All this years images are with the asi224 and the 20" and a few with my 18" f3.3 newtonian.
