I am re-opening the darkroom in a local art center. The school district and county have helped with the remodel and new sinks but I need new enlargers. The darkroom is only one small part of a major overhaul and money for better equiptment will be available in the future to those arts (painting, weaving, pottery,etc...) that have interest from the paying public but first my job is to just get things going with an "Intro to B&W Darkroom" class. I am interested in the Holga only because of the price. In two years I hope to sell them off for 23C's. My question is will they hold up for 2 to 3 years or are they junk.
