I once paid $1300 for the privilege of cleaning out a shop. I did it knowing exactly what was in there. I wanted the NAPA 5hp 80gal compressor that is like new, hundreds of pounds of stainless, titanium, brass and steel, Snap-On and other tools, lathe and mill tools, vises, hardware, anvils, bench grinders and too much more to list. Not too much went in the trash because that was already cleaned out. I have turned down other good offers because the amount of garbage going to the dump was not worth the time effort and expense.
