I GOT IT!
I found a guy on craigslist selling “4 old cameras”. He gave them all to me for only $25! One of them is my newly beloved, Polaroid SX-70. It’s not modified yet to be compatible with the 600 film I have stocked in the fridge, but I was too impatient to wait. I blew out a few pics, but at least I got a few good ones.
