Thanks for the information. I've got the foot pump for my 3006 tank as I've been using 4x5 for a good while and totally agree it's not really a luxury. (before I got the pump I was stupid enough to blow gently, and then a bit harder into the opening - sealing it of course so as to pressurize it... I didn't lose (or loose) any teeth but I did buy a pump right away.)
Back in the '80s before I got the Jobo, I use an old Unicolor 8x10 paper processing tank on a Unicolor roller and discovered the hard way that it needed attending, even when the thing was totally level.
Now I have to talk my brother into springing for the 3005 drum...
