Recommend CRM system

Hi there,
I am looking for a crm system, which can manage a database for 3 different businesses, but who may have mutual clients

For example a furniture business, an auctioneer business and a hotel. There maybe a crossover in some of these businesses, and therefore can market depending on the offer etc.

I hope you can help me.
I have looked at one page crm and zoho, but is there anything else out there?

Salesforce.com I believe they offer a free 30 day trial.

Sage ACT would be one of the leaders at the low end of the market. MS Dynamics is a dearer option, with tighter integration with Outlook. What exactly are you hoping to use the CRM for?

Be careful about any data protection issues arising from sharing data across different businesses.

You should also look at some of the open sourse options - google for details.
