Hot take: a $60 parts body from a flea market in Tulsa saved a job I almost turned down
Spent last Tuesday deep cleaning a Nikon F3 that sat in a flooded garage for 8 months, and when I finally got the shutter firing right after 3 hours of fiddling, I realized the whole fix came down to a $4 light seal kit I ordered on a whim, so what's the cheapest part that's ever rescued a repair you were about to give up on?
