If for "couple hundred quid" extra you get to do it on a full motion sim then why do it. Do it the cheapest and most efficient way. As I said above the MCC and renewal was conducted by Multiflight. The renewal itself cost me no more than £140 (can't remember the exact amount) including the sim end examiner's fee (it was arranged during the course BTW). That's where the real saving is compared to a full scale one.
Keep current and save your couple hundred quids for later. When the day come for you to have a sim ride/interview then use the money saved to:
-Use Andy Mattock's trident (did it and it worked for me)
-Get a deal through the unemployed pilot register at LGW to use one of GECAT's sim. Good if you know you will be "simming" on a 125 for example.
Or if you know the sim ride will be conducted on a FRASCA (correct me if I am wrong but I think KLM used to do that) then find a place who have one and practice what you know about the profile.
I really think you should make the most of your MCC course by learning something from it so even if it looks like a tick in the box, who knows,it might be useful some day...
But It's your money so spend it the way you like (and I can see why a 1011 sim can sound good

) and all I am saying is that perhaps a better timing and more trageted use of those "couple hundred quid" can make the difference later, bearing in mind that going on a full motion sim today is unlikely to be helpful tomorrow (talking for wannabes not for guys who need to keep current on type of course).
Things are turning around so let's get ready for it.
