Hi Richard.

If you are going for solar system objects, (don't forget asteroid and widefield with a suitable lens for meteors) then think about exposure length and small pixel size. Around 6.4 microns is a good all round pixel size and the ability to go for at least a minutes exposure avail. Longer would be better. Add to that next a good frame rate with minimum compression.

Colour is a personal choice, I like mono, you then have the ability to add various filters later on, not just rgb but Ha and others. Or you could go one shot colour. If you are doing luna and solar mainly I'd suggest go for the mono. But starting out on the planets then one shot colour would likely be the go.

There are plenty of cameras around that fill those criteria in a very reasonable price range. I have tried the DBK31 and must say I am a bit disappointed in its sensitivity (and willingness to work with other softward). I have only really used it as a guide camera and found it lacking. I can't say how it would go as planetary camera. I do know though I had issues with getting the settings right so that Registax would open it. Mono I love my DMK21. Its a fantastic little camera for me and a good step up from a OSC.
