CFBuilder versus CFEclipse

I would wait if I were you... CFB is in its infancy and I encounter just as many problems (though different) in CFB than I did in cf_eclipse. I haven't checked in a while, but if cf_eclipse were to fix some bugs, it could be a great cf editor. However, it doesn't support line level debugging, which is a huge benefit of CFB. If that's important, it might be worth the $300.

The CFB editor sucks right now, and it has since I started using it (last winter). It's slow and painful to edit some files. They've made some fixes in the first update that were much needed, but now they need to deal with performance. Some files cripple the CFB editor and it takes several seconds after every edit for the editor to catch up. There's also a ton of features that I don't use, which have to do with automatic code generation and so forth.

If you are to switch, it takes a little time. You have to re-import all your projects and then configure RDS. It's not entirely straight forward and it might take a little time for you to figure it out.
