Alaina, Setting up a dark room can ba as expensive or cheap as you make it. From my experience there are alot of people who find an enlarger in the basement or attic of the house and sell it in the classifieds for practically nothing. sometimes even with trays and chemicals. The most expensive part this way is probable the paper. When i built my first one i used ( tho i wouldn't recommend it ) aluminun oven trays... real cheap. my advise is if you want to set one up, watch the classifieds. Sean(posted 9210 days ago)
