If only 100mA or so, and less than 7V... Once i used 74AC04 parallelled inverters as drivers for very small brushless motor.  Very cheap and low voltage loss, usable between 2 and 7 Volts (depending on manufacturer).  Look in manufacturers spec.  Note the very fast switching might lead to radiated EMI.

Another idea is to look at bus drivers.

I remember also looking at rail-rail output OP-amps.  A few have strong output.  Alos look at headphone drivers.  Too expensive then, but have dropped in cost since.
