I wouldn't touch Rocky Mountain with a bargepole, the company has been in financial difficulty for a few years and apparently a lot of people have sent stuff in and never got it back and when asking just been given no answer. Apparently the owner is extremely difficult to deal with.
However Process C-22 (In the UK) as well as Film Rescue (In the USA) International can also do it.
There is one group trying to resurrect a K-14M line as the relative chemicals etc are on the patent issued to Kodak in 1978 (approxiamtely) as well as the updates to it when the formaldeyde had to be removed. Kodak may even release how to make the chemicals like they have with the E-4 process.
There are also some K-lab minilabs (an attempt by Kodak to make the film more profitable about 10 years ago by having more processing facilities, but ultimately didn't help) still around.
At least its not as complex as the original K-11 process in 1935 where you had to use dye bleaches instead of re-exposure to light which ended up giving it about 32 steps!
Still for that price its not worth it.
