Well I got my MCC certificate from Multiflight for around £2K - good instructors - most were active airline pilots so each sim session tended to have a slightly different emphasis - I really enjoyed it and it only lasted 8 days.
I got the required piece of paper so I am happy, if you do a search I am sure you can quite readily discover a number of debates about sim types for the MCC - might get asked at interview but it isnt really relevant to the actual MCC course itself.
Have fun
Ben
