I think you should almost always call.

UNLESS you've limped in with crap and you shouldn't be in the hand to begin with. In that position, fold and save the bet. the flop ain't gonna help ya.

I read somewhere that if after you limp and someone raises, if you reaction is a *groan* and you're bothered by the raise, its time to tighen up your limping requirements. I think thats great advice.

If your cards justify you being in the hand, then they justify calling the raise.

Now on the other hand, when do you want to be the raiser? You want to punish the limpers every chance you get. From LP, raise with most hands worth a LP call, including middle suited connectors.
