Personally I do not believe any airline would take a consideration on what Sim you have done your MCC on. But for your own sake my suggestion is do it on an aircraft that you will most likely fly - 737/A320 and definetely choose an EFIS version just to get yourself getting used to modern aircraft and instrumentation. Bournemouth is great place, so as EUROPEAN but the simulators there are quite old and this is the reason to be cheap - all are analogue. At OAA they do MCC on 737 with EFIS and wasn't that expensive - £2,5k I think it was. I did mine there, but on the CRJ as wanted to go cheaper (it was £2k), still glass cockpit and don't regret doing. Generic simulators e.g Kingair will not differ to the MEP sim you did your IR in, so it will be easier for you but you won't learn new things.
