Here are some options

You can use SugarCRM paid edition or you can also try the Open Source Version.

You can also try kayako.com they have a nice system.

And you might want to look at Salesforce.com, I would say they are the largest on the net and have the most relationships. The only thing bad I can say about this is the cost is high.
