After looking at the demo, I am really impressed. Looks like it's ready to go with little set-up. I also like that you can access it from anywhere if you have web access.
Not sure I want to swallow $25 per month since I have a pretty small book right now. I would sign on pretty fast if I had a bigger book. I am looking at the free SugarCRM that Al suggested. Not sure if I want to take the time to set it up though.
