Rom,
Since you will call Calumet also check on tray stackers. The advantage (if you have the room) is that if you want to make larger prints ie 16x20 you can stack three trays in just over the space of one. You may already have trays. I happen to have a large sink so with two of the tray stackers that hold 16x20 trays I can have six trays in just over the space of two.
