i think early stage limping with small pocket pairs is ok, but late stage with antes and stuff you should rase 77+ and fold the rest...Unless you are Big blind, you could limp with small pocket pair if someone rase and try your luck hitting trips...
There is no "early stage / late stage" in a full ring cash game, like the OP is asking.
To respond to the original question: It depends on your opponents and the raise size, if you're worried about "getting the right odds". In theory, if you limp a small pocket pair and get raised 3 or 4 times, and, both you and your opponent have decent stack sizes (in theory, at least 12 times the size of the raise), and, you think he will stack off if he has an overpair or top pair those times that you flop a set, then you might be playing correctly. These odds improve somewhat if others call the raise as well because your implied odds can improve.
If, on the other hand, your opponent is a decent aggressive player and is attacking you for open limping from early position and won't stack off with just top pair when you flop a set, or you or he have less that 12x the raise size, or, if your most of your opponents at the table are weak-tight and would fold preflop if you had raised your small pair or fold to a continuation bet on a dry flop, then you're not playing correctly by limping from early, because you should have raised in the latter situation and folded in the former.
It's just not that simple.
