+1 @ bare bulb and the old Sunpacks (e.g. 622). That or something like the Armatar flash which also will take securely mounted modifiers. Sadly, my Armatar bit the dust a while back, and of course didn't have contemporary electronics / ETTL.
Radio enabled Armatar, ETTL module capable, old school auto/ec capable, secure modifier capable, external battery source capable.
+1 @ knobs (digital readout accuracy) instead of 15 button pushes to move 1.5 stops or some two button combination for a full stop and 5 more button pushes afterwards, etc.
