If I was you I'd ask my current employer for 3 months leave of abscence. That or burn up all your leave owing and perhaps take some in arrears or without pay. Do the first 3 months as a taste test. Be the contract good or bad make a decision then. If you cannot get the time off I wouldn't touch it. Job paying the bills is better than no job at all. I'd only do it if the money was extremely good and by that I mean 2 or 3 times what you're on now.
Good luck
