I use GarageBand for my projects. I like it , it was free with my Mac, and I've had some great results. That being said it is a bit limited but some times it helps me to think outside the box. To the point, Apple has launched iLife'08 and GarageBand has some new features. For example you can now automate your effects in the same way you could previously vary pan and volume. There is also a visual eq that lets you drag a curve to vary your sound and I think I saw an analyser in there also. All this said the virtual band set up looks a bit naff. Anyway love to hear your thoughts.
