Tim,
Missed this the first time around - Thanks for the bump.
I haven't used it, but I've heard NetBeans and IDEA have good Ant support. Then again, so does RAD (the paid version of Eclipse.)
It's hard to recommend a good IDE that everyone will find good. What kind of code do you develop - POJOs, web,
EJB, etc? If web or EJB, what server do you deploy to? Sometimes the integration is a deciding factor.
