New to SNG's

[Poker Junkie]

Hello all, I have a question that I'm sure is pretty basic but would like some input on. First of all I have been playing seriously (are freerolls serious?) for about 6 months and have read several books (TAP, Low Limit and some others before I found this site)Unfortunately I shouldn't have wasted my money on some of the others. I recently won $20.00 in a MTT (freeroll) and want to try and build up my bank roll. I have been playing $1+.20 SNG's and $2+.20 SNG's not enough for any type of data analysis.

Are these very low buy-in SNG's to "loose" to use some of the outstanding things I have read on playing the 10+1 SNG's by Aleo Magnus and others? Is there another link for a separate strategy for these smaller SNG's?

Thanks,
