No need to spend that much, you have much much cheaper alternatives like this. They're not the ultimate optical quality you need to perform an estapedotomy, but they offer great depth of field, little chromatic aberration and sharper image than any magnifying glasses. If you want much better quality, they've got this Leica model (we have one of those at our clinics) which I'm sure is not that expensive compared to 35 or 25K bucks. On the cheap side of things, yet with very good quality (we have one of these too) the Optomic is rather decent, I would operate an ear with it, so probably I could do a few things else. You'd need to ask them how to mount a video camera on it though.
