I use this conduit, worked first time no problem. My advice, which might not be that of others, is ditch iSync and use this.
First, you'll get maximum productivity out of both your palm and Entourage.
Second,it has never let me down, something I cannot say about iSnyc.
If you are using Entourage you have already overcome the 'feeling' of not using all the knobs and whistles of Jaguar; mail,iCal & addressbook, so letting go of iSnyc shouldn't cause too much heartache.
Hope this helps
