Have you used Mint.com?
The only small flaw it has is that you can’t truly track cash spending very well. You have to “split” cash withdrawal transactions into the various ways you spent that cash. Otherwise, it has brought much clarity to people’s financial situations, in such a pleasurable way. The site design is handsome and easy to use, and the trends and transactions features are SO HELPFUL.
