Looking at E-Bay average US$ pricing, and including shipping and converting to $CDN, we have a $160 collection of 3 vintage flash units. Offered here on Kijiji at a bargain of $10 CDN for all 3, to own a piece of up to 40-year-old photographic technology. This price is a huge discount (about 94%) from the on-line market. A “must have” for the camera aficionado or collector. These would look great on a collection display shelf or test your skills with old fashioned film photography.
