Extracting ActionScript from SWF

Has anyone come across a good tool for extracting ActionScript from an SWF.

I am working on a project and lost 2 AS files. I’ve tried extracting all of the AS code from the project using Flare (http://www.nowrap.de/flare.html), but the code that Flare generates is pretty useless for me in terms of trying to recreate the lost files.

In particular I’m interested in SoThink’s decompiler (http://www.sothink.com/product/flashdecompiler/index.htm) and Trillix (http://www.eltima.com/products/flashdecompiler/).
Anyone had any luck with these?
