So I'm looking around for a guide camera, just looking for some feedback from experience or other options.

My requirements: SHORT TERM, will be used with a mini finder scope type setup. Will be guiding a DSLR with focal ranges from 14-620mm.

LONG TERM, Will be guiding a 500-600mm f5-6 (I want something fast, so whilst f6 will be an option I'm hoping for something at f5) scope with an ASI1600, hopefully with an OAG. Needs to work with PHD2 for guiding and I'm hoping to use it with sharpcap for polar alignment instead of getting a polemaster (hopefully its as easy as a polemaster sounds, or I will probably just end up with one of them too).

options that I can see:
$279 ZWO ASI120MM 3.75um pixels 1/3 inch sensor. I like the price of this camera, but with the long term view including an ASI1600 I'm not sure if running two ZWO cameras would cause driver issues.

$355 QHY-5 II 5.2um pixels 1/2 inch sensor.

$360 QHY-5L II 3.75um pixels 1/3 inch sensor.
