Moneydance 2006 - cross-platform finance management
Moneydance 2006 (awkward name and all) is a well-rounded personal finance app with a nice selection of features including: online banking and bill payment, budget management, recurring transactions, investment tracking, report generation, Quicken/Money import, database encryption and a whole lot more.
It might be missing a few features when compared to big dogs like Quicken 2006, but it's priced accordingly: a license is $30 no matter what OS(es) you need it for, and when I say cross-platform, I mean it: Moneydance 2006 works on Mac OS X, Windows, Linux, Solaris, OS/2, and Unix.
A fully functioning demo is available that allows for entering up to 100 transactions - so what are you waiting for? Go grab a copy and stop making excuses for ending up budget-less and broke every month.
