I'll second the comments on the QHY8 series. My first CCD, bought new in, iirc, 2009 was a QHY8, for use with my 8" newt. It was a fine camera, and gave good results. I then on sold it to buy a QHY8Pro, as I wanted to get into Hyperstar with my new (used) C8. It also was a fine little camera, good cooling, and I even purchased a QHY9 Mono some time later.
Just to maybe save you the Google, here are some comments on Stargazers lounge:

To cut a long story short, I was out of astro for some years due to house build etc, and the QHY8 Pro was in various plastic storage containers for over six years. I pulled it out about a month ago, and it still works perfectly. I was going to sell it and stick with my ASI183MC for wideband/Hyperstar, but the larger sensor size and thinner package has persuaded me to keep the QHY8 Pro.
If you can find a QHY8L or Pro, and the price is right, strongly recommended. It should be far cheaper than a new CMOS unit, and for starting out is a good choice. The only minor nit pick is the dedicated power box that it uses.
