Over the years, the best has been a Leica M2 with a 35mm f2 Summicron for $15. Also a near mint Nikkormat FTn with 35mm f2 for $5, a Yashicamat 124 for $5, a Spotmatic with lens for $25, a Pentax Spotmeter V for $2 and a Nikon SB-600 with some other things for $15. I have found studio flash equipment at garage sales and flea markets also.
