I for one think that the prospect itself is rather attractive - combining ACCA with an MBA with a low cost/time commitment associated is an good proposition in terms of career prospects if one think of becoming FD (like I do).
I was thinking of an MBA regardless, but when I looked around at the programmes that my friends tell me are highly-regarded (aside from let's say London Business School- I don't think most of us consider this as an option), I'm rather annoyed by the fact core modules include stuff like Accounting & Financial Management (at Warwick) or Accounting Management Analysis and Financial Management (Imperial). Some people may think it's an advantage (easy modules for someone who has done ACCA) but I think it's a waste of time - I'd rather move quicker to getting this higher salary virtually all MBA graduates get.
In terms of accreditation, I don't think it's as important as often suggested, unless you work for a large enterprise with very rigid HR/career development procedures - most employers I think look at the skill-set you bring with you and the MBA certificate is just an additional proxy for assessment (albeit a strong one). In any case, I don't think an MBA from -any- UK uni can be unattractive to employers - some shady ones from correspondence courses with universities in Bangladesh may be looked down at, but from what I've seen on both LSBF's and UEL's website it looks like a genuine, credible degree.
Are there any current students on here who can spare some advice? I'm thinking of possible starting this in January.
