I did mine at CRM Aviation at Cranfield.
Sim was great and so were the instructors I had. Didnt encounter any problems and learnt a lot! So much attention was spent on the MCC side of the training, it was very idfferent to the Single Pilot stuff you do for your IR and I felt like to really had got to grips with working as a team in a faster aicraft and managing the whole process well.
I got mine with them for £1499, and I think it still is that price. I've also just used my 2 hours free sim time with them that you get after the course - as I have a kinda 'assesment' comming up after Christmas. This was really helpful! They have also told me that from the new year they will also have FNPT II approval for a brand new complex twin simulator and im 'gunna' get a 10% discount on the renewal training and renwal if i choose to do it with them. Bargain!
The only problem I had when i was there was a fault ADF unit, but as the course was mostly about the MCC side of things it really didnt matter too much.
I have also heard good things about OAA at Oxford, but i cant give any info on that. I do know someone who can though if you want to PM me. Think its a little more pricy.
best of luck with the course! Its about getting the most out of it and learning to work in a modern cockpit as a team! Not about fancy moving simulators! Enjoy!
