I'm certainly no fanboy for ZWO products. However, based mostly on the excellent results and favourable comments of John Graham, I jumped in and bought the ASI071.
Certainly not as a substitute for my CCD cameras, but rather as a DSLR replacement. I've mostly used it so far on comets and bright DSO's, where it's proved itself admirably on image quality and operational reliability.
None of the problems stated in this thread have affected my particular camera. It's operated flawlessly, thanks in no small part to tips John Graham gave me early on. Or... maybe I just "lucked out"??
I have no doubt the QC at ZWO is hit and miss. Several friends have returned failed ZWO cameras and accessories. ZWO really needs to fix that part of their business.
Currently, I'm looking at how the Monochrome Full Frame CMOS market develops. For what a reliable camera is likely going to cost, I sure won't be taking any chances with a poor quality manufacturer.
