Thrift store junkie here.
Camera buying can be hit or miss. Naturally you don't go "I want a Contax, let's see what Goodwill has." You get what they got, if they have anything. Sometimes you see a "your free gift for subscribing" camera for $15. Sometimes you find an Olympus Mju:2 for $5. Sometimes the battery compartment is caked in akaline battery leak. And sometimes you find a roll in them forgotten by the last owner.
Highlights of stuff I've found. In all, I probably paid around $100 total for these.
XA in box
Mju:2, two of them
Shit ton of Stylus Epic 80s
Nikon Lite Touch AF
Sekonic L-358 light meter
Superheadz Ultra wide & slim
Nishika N8000, new in box. Sent that guy straight to eBay.
Pic, some cameras I have lying around. Vivitar is in plastic because it had a pretty bad battery leak. But it's so delightfully cheap looking I want to get it cleaned up.
