Yes, Tabasco! Rechargeables are great! They don't seem to last as long between charges as regular disposable batteries, but as long as you have some on hand, who cares? Just switch them out. We have a "dead battery" dish and "charged battery" dish. As soon as there are 8 batteries in the "dead" dish, they get charged. That way all we have to do is swap them out!
I sure wish they had chargers for C and D batteries. Those are the ones we really go through... baby swings, vibrating chairs, etc. A C/D battery charger would be like the best new-baby gift ever.
