Q:

Websites for 'Normalizing' CSS?

I recently found the Ultimate CSS Gradient Generator site for easily generating CSS gradients across all browser platforms.  It's perfect for what I was looking for.  However, I've also encountered other aspects of CSS that require multiple declarations to be cross-browser compatible (i.e. anything like -webkit-*).  It's a pain in the butt to develop using multiple browser types.  I prefer to develop in Firefox with Firebug for initial testing, and then obviously do cross-browser testing as QA.
My question is, does anyone know of sites that will let me plugin my existing CSS (which may be Firefox or Safari or whatever-specific) and have it 'normalize' it with the appropriate browser-specific declarations for other browsers?  Say, for example, I have something like this in my CSS:
-moz-border-radius: 2px;

I'd like to be able to plugin a CSS file that has those declarations all over the place, and have the site also add things like...
-webkit-border-radius: 2px;

(and whatever the equivalent is on other browsers)
Anyone know of a tool or site that will accomplish this?  It obviously doesn't eliminate the need to do extensive cross-browser testing before shipping, but I would imagine it would reduce development time significantly.
