Do you mind providing the info like others have in the post and I'll re-publish the list with you added? I like keeping a morbid curiosity tally.
I think repair might well be a better option. Info has been thin on the ground as to what is wrong with them but there obviously is something up here. There have been one or two posts hinting at an improved part. I want to make sure these are all tracked so that if we start seeing futher failures we have a repository to say - hey, what gives - if we start getting the out-of-warranty run-around.
I received a replacement unit that was two months older that my first unit (still new in box) with brighter corners, and a bit quieter e-shi(f)t, slightly better convergence. So if you are otherwise happy a repair is perhaps a good option due to the natural variation in these units.
Re: your calibration - even if it were reset, if it is the same unit you can assume anything that was set up in the menus you could have copied down, and I'd imagine that you should probably even be able to restore your autcal setup if you have it from Chad. Assuming the iris settings he was able to get to work actually remain in more or less the same place after repair (not a given).
That is all assuming that for simplicity sake they don't actually replace the entire optical block when effecting this iris repair. in which case you might not be any better off ref: many of the inter-unit variances.
