We are looking at getting the Zimbra Connector for BB for the 20 or so employees here we have with blackberries.

I currently do not have a BES server, from what I understand...

There is zero functionality between zimbra and BB's without a BES.

Other than the simplified web interface, there is nothing that zimbra offers to the blackberry (8830, 8330.. ) without the use of a BES server. (right?)

(from those that have BES') what is the approximate cost of BES for my 20 or so users, and is the cost for the BES and the Zimbra Connector worth it?

Thanks in advance.
