I got this a while ago. It really is a great app, more than I even need at this point (college student). Very well organized, simple but effective and detailed interface, and a LOT of small things that make it a great app (the summary area is really nice, and making custom summaries is really easy. The only thing I could ask there is regular expression support... but that's a bit geeky).

If you need to track expenses, it's fantastic. Cheap as far as most apps go, and very well designed.
