I politely disagree on the 40-60 number. POGO sells the holder for 66 bucks right now, the lens has got to be 50-75. I would expect to see it on a table for sale in the 125 CDN range.
I believe you can buy one new today for about $130 from most vendors.
It's a used reproduction, $50. Is more than fair
Don’t know why anyone would pay $125 for it when you can two lens and a body for $130 no savings there . Price of Gas and all !
