We Buy and Sell Used Equipment. On the basis that one man's rhubbish is another man's gold, we regularly buy college equipment, repair and refurbish where necessary, to sell to our customers at prices lower than eBay with the surety that you are dealing with your favourite supplier! The range of product we purchase includes enlargers, enlarger lenses and accessories. Film and old DSLR cameras. Out-dated film and paper or any excess stock that is no longer required. Typically we will offer the college a credit note rather than cash against future purchases.
