When u have the button, what hands will u play when the CO raises for a blind steal?

In the 2/4 and 3/6 limits this is happening to me frequently and I think Im passing up some +ev situations. I usually fold all but the best hands.

Now I know this is situationally dependant. And more importantly player dependant.

But should I start fighting back like it was my big blind?

I really get tired of folding my hands from the best position.
