just remember not to blast your moneysite - use SB to find good high PR urls you can manually comment on for links to your money site - otherwise use it for blasting backlinks to your tier 2 sites.
You can find AA lists on this forum for free to get going, but these are often spammed to death. To get good results you must learn to build your own AA comment and trackback lists, or purchase good quality AA trackback and comment lists - you can find providers of those in the buy/sell section on BHW if you dig around a little.
If you use SB wisely, it is an amazing tool, and can really do so much more than simply scrape and post.
