NLTRN limping from the button?

[rebel_dk]

I am playing 10$ HU SNG regularly and I am showing a nice profit. I am somewhat nervous about going higher, but I have been taking staps as well as watching others play.

My prefered style of play is taking down a lot of small pots and I generally prefer not playing big pots since I feel I don't need to take coinflips against worse opponents.

At the higher buy ins, my edge won't be as high as in the 10's and I get the feeling that limping from the button is generally a very bad idea and that I should adopt a fold or raise attitude. Does limping just invite opponents to attack (which of course could be a good thing)? How about min. bets preflop (especially on the lower levels), useful for building pots with pos or just lame because they offer excellent pot odds?

I know this is a rather general question, but I do get the feeling that most 2+2'er ppl adhere to the "always" raise from the button rule.
