I haven't read anyone suggesting John Sexton's slosher. Its basically a tray with dividers. Mine is homemade from a paper developing tray with glued in plastic dividers with plenty of holes to provide for agitation. I have tray that hold four or six 4x5's and one that holds 4 5x7s. If you make it yourself its dirt cheap, easy to use and sinece the films are separated no scratches. I am sure that the various tube systems out there are great but I am too cheap to buy them and to lazy to learn their use.
