I guess I was thinking more "local market". I know that anything (Isuzu 2.3 / 2.6) that comes into a boneyard down here, the engine is gone within a matter of days (unless bad thrust bearings). Likewise, when I had a few Isuzu parts on my local craigslist, folks were emailing me looking for engines.
I agree, with expensive and cumbersome shipping, a shipped purchase is most likely out of the question. I ended up taking my MUA5 to the dump because nobody wanted it - even for free.
