Best Clientscript That Combine And Minify Css/js

Searching for the best ClientScript that combine and minify CSS/JS

I’ve made a modification over original EClientScript (extended CClientScript)

that uses stronger hash involving mtime of all files

also some people noted minscript (but by looking at its code I see that each hit to JS/CSS would be php hit)

it there any extension where you can exclude the files from being minified or compressed?
