Host Based Intrusion Detection

I am needing to deploy a host based intrusion detection system as recommended by a security audit team. I know of AIDE and Tripwire.  Is there any other solutions?  What are the experiences that people have had with any of these systems.  Any system worth anything would need to detect automatically an unauthorized change and send an alert.  The platforms this would need to support is RedHat, Solaris, and W2K server.

Thanks in advance,

Ron Leedy
