Doug,
The wet mounting accessories came with the machine. I bought a "new" demo unit direct from one of Screen's sales rep's. I don't wet mount as a general rule, only when I am working with film that will benefit significantly from wet mounting (e.g. badly scratched).
I imagine, like anything, in any high-end equipment world, they could be expensive separately. However, there is absolutely no reason why you couldn't wet mount without any accessories as long as you do it carefully.
