I needed to drift align via (PHD->Indi) blind to the pole a week ago while on vacation with an astrotrac mount. I'm unable to use exposures less than about 7 seconds for the ASI120MM camera, less than that and I get the framing and exposure errors typically seen with this camera. I've updated the firmware to -compatible, high speed off, 8 bit. I'm on a Mac. While this will work for guiding it would be nice for drifting to be able to use a faster rate.
1). I assume my experience is normal with this POS camera?
2). Any recommendations on a better guide camera under indi; lodestar or sbig st-i ?
I don't know about the QHY5-II mono camera, but I have both the ASI120MC (USB2) and ASI120MC-S (USB3). Even after flashing the USB2 camera with the compatible firmware it didn't work for me on RPi3 or other Linux machines. The USB3 camera works like a charm though, also on OS X.

Thanks guys. I tried the camera under Ubuntu and although its much, much better, it still occasionally has the framing issue at a 1 second exposure. Seems fine at anything above that. Looks like it is unworkable under osx though. I'll look at getting the USB3 version.
