I have reviewed EE and find it to meet most of my needs.  However, I would like an online calendar like google calendar, ical, etc. Is there a module for this?  Any insight is greatly appreciated.

EE has a native calendar as part of the weblog module- check the docs for an overview.  Keep in mind, it is pretty simple- not on the level of iCal and it doesn’t handle recurring events.  (There is a third party plugin that allows recurring events.) It depends on the features you need whether this will fit the bill or not.

Have you tried out one of the trial options?  You’ll get a better feel for how it works if you can test it out.
