Freeware favorite OnyX goes 2.0

Whenever we write about Mac OS X utilities for system maintenance, our readers always remind of us one freeware utility that does a lot of work at no cost -- OnyX from Titanium Software.
This multifunction application does verification of your Startup Disk and System file structure, performs a lot of miscellaneous tasks for system maintenance and cleanup, and lets you configure some hidden parameters for the Finder, Dock, Dashboard, Exposé, Safari, the Login window, and even some of Apple's applications.
The improvements in OnyX 2.0 include faster operation, and deleting the applications cache, Internet cache, and logs has been improved. Most of these improvements are due to the application now being complied with the latest version of Xcode. One new feature lets you rebuild Mail's envelope index in the automation panel.
While the version 2.0 download is only available for Leopard, you can also download earlier versions for Tiger, Panther, and Jaguar. Support is pretty good; it's done through Titanium's forums and there are always answers available for most of your questions.
If you don't use OnyX, what's your favorite free Mac system maintenance utility?

Any update to Onyx is welcomed. Great app, even better price.

I've been using Onyx since OSX 10.2, and I've come to consider it the best freeware maintenance utility out there.

have you tried using IceClean? Im just wondering if I should switch from it to OnyX.

I use IceClean. Anyone think Onyx would be a better choice?

Leopard Cache Cleaner doesnt look free to me...says its shareware...so therefore it costs money to use
sorry to dampen your excitement but this article asked for other FREE maintenance apps that we use
i use IceClean...but what i like about it most is if something isnt deleting from my trash...and i know im not using it...it will force it to delete...love it

i truly dislike OnyX; i consider it one strain of the virus that infects people with the urge fix things that aren't broken

I like Onyx but their website is and always has been painfully slow. I hate downloading new versions because it always take 30 years.
As I was typing this, the page finally loaded enough that I could click the download link and it actually took just a few seconds, so I guess I'll eat my words now.
