minify - Reliable and convenient JavaScript minifier -

i write javascript code. interested in minifying better performance, don't plan spend time on that, in testing minified result.

i found online service: http://www.lotterypost.com/js-compress.aspx

so couple questions:

• is reliable?
• microsoft ajax minifier vs. yui compressor, what's best option?
• any other similar online tool recommend (and why better above link)?

that link post happens 1 use too.

use ms ajax minifer. it's way better yui one. besides:

http://stephenwalther.com/blog/archive/2009/10/16/using-the-new-microsoft-ajax-minifier.aspx:

the microsoft ajax team (i work on team) has been using tool internally number of years. example, use microsoft ajax minifier minify microsoft ajax library before publishing it.

well if don't trust me, run source code (if don't have actual source code test, grab source @ http://code.jquery.com/jquery-1.6.2.js) through both , see more "minified".
