For what it's worth, I got 2 quotes, one from Nisonger, $171 (2 years ago), and one from West Valley Instruments which was a few dollars more. I went with Nisonger and the final bill came in at about $140 including shipping. I cannot account for the price drop but it would seem that they don't have a standard fee. It did come back as new.
I was not aware of Rimmer's reproduction at the time but probably would have gone that route based on the above quotes.
