At times we have all done well and snared good bargains. An AIS 28/3.5 Nikkor with four Nikkor B&W filters for $30. A Rolleicord Vb for $95. A Nikon N65 (aka F65) in pristine condition with lens, filters, a fitted case and other accessories for $50. A Nikkormat EL with a 50/1.4 Nikkor SC for $55. Hasselblad bits and pieces (in the good old days when I owned 'blads) for less than $25.
Late in my life I have concluded it is best to buy fewer items and pay more for good quality. And use the gear.
