Huh... Nice find! seems like every time I checked them in the past they were Hella' expensive compared to other sources... of course i was buying repair manuals for my 1980s Toyotas instead, so that might of been why!
First thing even before i bought my LS was got the wiring manaul from faxon, 40$ IIRC, i love it! Only gripe is they dont have a fusebox diagram, need to backtrack it thru the wires on the specific page.
I have a pdf format of the FSM, but i do prefer the hardcopy.
