ways to sync Address Book and Entourage X

Dear MacFriends-

Forgive me if this is discussed elsewhere in the FAQs (I didn't run
across it). I am looking for a way to synchronize my contacts in
Entourage and AddressBook. Ideally, I would like a freeware solution,
but I'm willing to pop for a shareware solution (up to $25 or so).

I do know about vCard drag-and-drop, but find this very cumbersome for
managing incremental updates to my contacts. Also, it looks like the
fields in Entourage and AddressBook don't match up fully. My main
contacts are in Entourage, and I like Entourage's contact management
interface, but a few new things get added to AddressBook from Apple
Mail, which I've gone back to using because Entourage can't read
dot-mac and my other accounts get spammed so much I've started routing
all my real mail to dot-mac. Since I'm using Apple Mail as my main
mail program, the contact lists in Entourage and AddressBook may start
to diverge if I don't have a real synchronization solution, and I'd
like to be able to sync my contacts onto my iPod. iPodIt does a nice
job for Entourage-iPod contact syncing, but the contacts from iPodIt
don't get sync'd back to AddressBook with iSync AFAIK.

Any advice or suggestions?

Thanks
Bruce
