Exec education / master / online class

Hi,
I've spent a bit of time in consulting (13 years..) doing market analysis for due diligence / strategy development and am keen to learn more on financial modeling (project finance and co). I have a tiny bit of exposure to financial modeling but would like to get more exhaustive knowledge (to potentially move to finance department of a company). I'm considering:
- exec education - but programmes seem short (LBS/other in Europe) / not deep enough
- evening / online classes
- perhaps full-time master?
Any advise?
Thanks a lot
S
