My only concern would be in buying something that I cant collimate myself with some patience and care (I used to work on a RADAR system where aligning the electronics on a particular "drawer" with about ten modules in it took a couple of days. Mirror I can understand, it is in a cell and should be set once in the factory and generally not touched again, just like my C925, but I would have to be happy to tweak the collimation screws in the lens cell in the corrector to buy one, I am a born "tweaker" though..

If you are doing EAA I assume you would be using fairly short exposures? Like everything else, the reflection issues I could see with my 294 (Is yours the cooled version?) were more and more prominent the longer the exposure and the brighter the star in question. I found the other forum so I will have a look at images on there.
