Looking at Linear Technology we see comparators with propagation delays as low as a few nanoseconds to those into the hundred microsecond range. And there are comparators that sip power at the microwatt level to those that consume tens of milliwatts. You can also chose the package; small surface mount, such as SO8, to leaded 8 pin DIP packages. And last but not least the supply voltage ranges from 1.2 to 40 volts.
A versatile comparator available in a DIP package is the LT1017. It has a prop delay of 22us, needs only 30uA of supply current, can work with a supply from 1.2 to 40 volts. Two other important parameters are the input bias current of 15nA and an input offset voltage of 1mV.
