To talk me out of the following:

2x RB67 Pro S
50mm 4.5
90mm f3.8
180 f4.5
2x Polaroid backs
2x 220 and 120 backs
2x metered finders
2x WLF and a macro finder
30-50 refrigerator-kept rolls of 120 and 220 slide, BW and color

all for 450

I would be abandoning 35mm save for a compact Nikon prime, an EOS body and a Soviet rangefinder, and could probably pay for the entire thing by selling my Nikon kit which is all fast primes

...and go
