Depending on your budget and software used, you could try one of the Imaging Source/ DFK cameras as both a guide camera and a planetary. They are supported on PHD guiding software on a Mac, have to check about the newer USB ones on Windows.
People use web cams for guiding and for planetary so even a basic webcam with the right stacking software (registax et al) would be a start.
I used this guide scope combo for ages and still have it. It's a great guide scope and also not too bad for wide angle imaging- if the focuser will hold your camera!!
Depends all on budget, aspirations, interest and futureproofing!
Welcome anyway
