It would seem to be common sense, but why not pay the tech an hour or two for diagnosis time and an estimate to repair it, especially since it is already in his shop? Invest some $$$ now and at least have an idea of what is in store before you make an offer. I don't see how it can be that expensive to repair, even if you had to drop a whole new engine into it you could find one from a recycler for $1500 or less I would think.
