Beginner Questions for online SNG's

[Jbrochu]

After watching poker on TV for a couple of years, I just recently started playing on-line. I read a few books, and played the "play money" tables for a while at Party.

I realized that it's going to cost me some money to "get educated" - so recently started playing the $5/1 tables at Party. I've been able to play breakeven ROI through 20 SNG at the $5 level (which I realize is a tiny sample), but I hate giving away the 20% registration fee.

I'm wondering if moving to the $10/1 tables is a stupid move so soon? I figure that even if I place IMO less often (a reasonable assumption if not a certainty at this point) I still might manage breakeven ROI because of the 10% vs. 20% registration fee. I might also learn more faster at the $10/1 tables.

Should I go with the certainty of being able to play many more games at the $5/1 level, thus gaining more experience. Or should I take the chance of playing less games at the $10/1 level, but maybe gaining more valuable experience faster?

I'm also wondering what books you would recommend for learning to play well at short tables? Harrington's book has been great for learning to play full or near-full tables, but I'm getting killed when the tables get to around 4 players.
