In terms of style, this one is nice as well: http://taitems.github.com/jQuery.Gantt/
If it wouldn´t be for using Ext.js and the large code size, this one is the most polished in terms of look and function: http://bryntum.com/products/gantt/
If you need any help with styling it a bit differnt, give me a shout :)
One thing that would be great to add to the overview (if you´ve still got the demo files) is how large the download is - it´s one of the things that spoke against Bryntum's solution (over 2 MB!).

It would be great if you guys could show off your skills in a optimized demo site...
GET ext-all.js 304 OK cdn.sencha.io 442.4 KB 253ms
GET gnt-all-debug.js 304 Not Modified bryntum.com 282.4 KB 251ms
With a clean Chrome, purged cache: I get "38 requests ❘ 829.55KB transferred ❘ 1.52s (onload: 1.07s, DOMContentLoaded: 1.07s)"
And this is still without making any effort to custom build Ext JS. We're using ext-all.js for simplicity, and to make use of Sencha's CDN which should speed up world wide access compared to us hosting a custom file.
Hope this settles it :)
It implements it really nicely...
