Well... I made a bet with the Snap-On man today and lost.

I was getting ready to jump start a completely dead turbo diesel Doka when
my local Snap-On guy showed up and told me the little pocket sized jump
starter he had could do the trick.  I told him that if it started the Doka I
would buy one.  He hooked it up, I glowed the plugs and it fired right up.
I now own one... for $109.  Pretty cool little tool.  Wonder how long it
will last.

Pretty much the same as this one on Amazon:
