Let me just quickly put this into further perspective by how many additional chips you MUST win on average after you hit your set:

[ QUOTE ]
1. Folded around to the SB, he completes. You check your pair:
implied odds: infinite

[/ QUOTE ]

0 chips from his stack on average. Easiest.

[ QUOTE ]
2. Folded around to you in the SB, you complete for 5, BB checks:
implied odds: 160 to 1

[/ QUOTE ]

55 chips from his stack on average. Pretty easy to do. If he has a hand every once in a while you'll make it up for a decent amount. If we're looking beyond the simple math equation for hitting a set, you should be able to win a few extra pots without hitting.

3. You limp your small pair, folded around to the BB who is the only caller:
implied odds: 53 to 1

[/ QUOTE ]

165 chips from his stack on average. This guy has to have something strong to build the pot from 45 chips to 330 (he has to be able to handle almost 2 pot-sized bets). And that's on average. He will rarely do this with a hand he didn't raise with.

4. Folded to LP who minraises, you call 30 from the button and the blinds fold:
implied odds: 27 to 1

[/ QUOTE ]

330 chips from his stack on average. That means you'll be playing a 660 chip pot with a LP minraiser who will almost always have trash to begin with. Not happening. Probably profitable against a very TAG EP raiser.

[ QUOTE ]
5. You limp from MP, folded to button who raises to 60. All fold to you and you call for 45 more:
implied odds: 18 to 1

[/ QUOTE ]

660 from his stack. Impossible. Essentially you must stack him everytime you go to a flop. Not only is it unrealistic someone will put the rest of their chips in everytime, they also have redraws which fix a limit on how much you can actually average taking from them.

[ QUOTE ]
You will also be more likely to lose your stack to a bigger set or straight when you hit.

[/ QUOTE ]

Techincally yes. But in most situations, the number of times which you will stack someone else grows faster than the number of times someone will stack you as more people enter the pot.
