Now that the 8 x 20 camera is finished and my first film holder is done and now light tight, I need to get into actual shooting and developing. I have the Park Seed Company trays for the negatives and silver prints, but I need some larger trays for platinum/palladium developing. I've already spent enough money getting to this point and am looking for a cheaper alternative for 24" long trays than standard darkroom trays. I've been searching Ebay for used trays, but the shipping costs alone seem very high. Example - a lot of different sized trays (including three 20 x 24 trays) sold for something like $13 but the seller wanted over $70 for shipping. Does anyone out there have suggestions for larger trays that are a little more reasonable in cost (like Park Seed Company)?
