High PP's

[3 minute hero]

This has happened me a few times recently, 6 seat NL .50$/1$. I am dealer and everyone folds to me, i have AA, KK or AKs - should i raise??
I am well aware that i should raise but for profitablity i have been calling with a view to extracting some cash from the blinds. This strategy has mostly worked but (as i am well aware) it can be dangerous. I actually feel annoyed when i win the hand because i hate limping in this position. Has anyone any views?
