Yeah beware. I'm in a very similar situation and I've found that people are asking me to come and and fly their piston twins and that "I should be done really quickly"........ do the sums and it'll cost me about $8k. I'm not paying that thanks. I'd rather pay for a type rating (even if it costs me more) as I can't see how that $8k in a piston will benefit me. Only thing is, I'm not sure if UK/Euro outfits will entertain me with my hours and experience and all my JAA Exams.
