*facepalm* YES, THEY DO for hand processing tanks. Search for Jobo 2401. Sheesh!
It strikes me that you're the only one complaining about this. Perhaps it's YOUR processing paradigm that should be questioned, not Jobo's offerings... A case of the tail trying to wag the dog perhaps?
Sorry forgot to delete that part, if you notice later on in the thread I mentioned that when I googled the JOBO tank I discovered that it was actually not JOBO. And was in fact a different tank altogether, I forgot to go back and edit this post my apologies.
