I have heard nothing but good things about Jetlinx who use BA Sims at Cranebank last I heard it was 2800, I believe this is about the norm, although there were a company in the north doing one for 1100 on a King Air sim. Most use the MCC as a chance to handle a jet in prep for a sim ride in the future and as a 'reward' for all the hard work on the ATPL. It is without doubt the best bit. When you start any type rating you do another MCC as part of it you just normally dont have to do the initial CRM modules again. As for getting a job as a result of your MCC, I would forget that idea the MCC is a box ticking excercise these days nothing more.
The only people who do that are CTC on their AQC course which is also an approved MCC course. It will set you back 6.5k, but then it is the cheapest route to a jet job. Of course you have to get selected and make the grade on AQC to get in their hold pool but if you havent done an MCC yet, I would seriously consider it.
