Steven, does it say who designed the optical system ?, because the CDK from Cerovola is his own design, and the Planewave design is from David Rowe.
I also agree with you that if the quality is poor, your accuracy will suffer, which in turn effects performance. This is where design comes into it, and again as you said, if either mirror was out by a bee's knees, then good bye sweet views, wheras other designs allow a better tolerance in some areas.
This is why many RC users tell you these new cheap RC will not be able to handle collimation or ccuracy etc, etc. But if done right, it should. But time will tell how good they are.
Plus Fahim, the CDK's have only come out recently, where as more people recognise the RC name and the stigma behind it. So it would probably be more a business decision i would say. Bit like the old Beta and VHS, didnt matter if Beta was better, they still opted for the VHS.
I'd like to hear from someone who has one of the new cheap RC's, see how they perform.
