The Jobo multitank 6 will process up to 12 sheets of 4X5 (on reels) and 2 sheets of 8X10 inside the tank with no reels.
You can use it with a roller base, but doing color in an un tempered environment might be tricky (though you can figure out a way to do that).
You can also do roll film in the same tank (with another type of reel).
Its the ultimate do it all solution for LF\roll film.
Which Multitank 6 tank can do the 2 8x10 films?
As far as I know, for 8x10, you need the expert drum.
