I hate to be the bearer of bad tidings, but there's very little chance -- at any price -- that you'll be able to salvage much if anything. The drive was both reformatted AND a new system + apps put on -- this has likely overwritten most of your old data.
Data Rescue 3's trial will let you know what's recoverable. Beyond that we're talking a couple thousand bucks for DriveSavers, and at this point I doubt they'd be much more successful.
Sorry.
PS. BlackBooks have been around since 2006/2007, and you never backed it up ONCE in all that time? I know now is not the time to lecture, but while I wish you all the luck in the world, I do also hope you'll proceed into the future a little wiser.
