Blackberry Enterprise Server Small Business for Exchange v2.1 w/ 5 Client Access Licenses. Asking $100US.
This can be upgraded to the latest version (4.x) through a service contract direct from RIM. A 1 year service contract for 5 users will cost approximately $700US. Provides 1 year of software upgrades and 1 year of phone support.
Without the service contract, this software is still provides BES functionality.
If you purchase a service contract you are looking at a total cost of approx $800US to run the latest version of BES SBE with 5 users, rather than a full new server purchase for $1499US.

Saves you about $700 if you want to run BES 4.x, or you can run BES 2.1 for $100.
