I prefer the VS IDE over flex builder.
You could also try FDT plugin with eclipse. Easy to intergrate SVN etc. Just expensive to buy is its main downfall.
There are 3 (commercial) VS plugins for Flex dev:

- http://www.ensemble.com/products/tofino.shtml
- http://neutron.sharpstyle.com/
I have no idea what they are worth but Neutron does not support Actionscript 3/Flex.
As suggested there is the free and opensource FlashDevelop IDE which is inspired by Visual Studio:
We will shortly launch the final version of the Amethyst Flash Platform IDE for Visual Studio. There will be a free (edit+debug) release plus a commercial release with a visual design environment, extensive code formatting, refactoring, simultaneous multi-SWF debugging, extensive IntelliSense and integration with the Flash IDE.

We now have a feature list so you can compare the free version of Amethyst (Flash Platform IDE for Visual Studio) with the commercial edition: http://www.sapphiresteel.com/spip.php?page=amethyst-feature-list
Hope that helps

Congrats to SteelSapphire for the launch of Amethyst Professional this past Monday. Looks to be a great Flash/Flex development environment for Visual Studio. Looking forward to completing the Amethyst WebORB integration for end-to-end development, debugging and deployment inside Visual Studio!
