I find normally with a one portal party a gadgie can last for ages without replenishing. Using gadgets 1/2 of the time and carrying top blue load of ammo i have normally been able to complete areas of the game without having to portal out and back. For info my last 2 man gadgie party was gadgie/priest with the priest multiing as a bishop after lvl 18. Both built strength first, priest piety second and gadgeteer vitality (lots of stamina and cc). Never needed eagle eye to hit and priest concentrates on buffing gadgie and bashing anything else on the head with his stun mace. Never had ammo problems, a couple of hundred lightning bolts is enough to see me through most areas with liberal use of gadgets
