Events calendar suggestions?

I'm interested in adding an events calendar to a golf site in order to be able to list visitor-submitted tournaments coming up around the state.

Anyone have suggestions for calendar scripts or software I should check out?

It is a MUST that the calendar work something similar to a web directory in that visitors would submit events using an online form, then I would log into an admin to approve/disapprove.

I also would strongly desire a calendar that provides visitors the options of searching by keyword, so they could enter the name of a city and see only events taking place in that city.

And I would also hope to find something where customizing the input fields for the submission form is relatively easy to do.

Any help is greatly appreciated.

thanks

Just wondering what language engine your site works on i.e. PHP, ASP, ASP.NET
Knowing this gives us a better base to make suggestions on.

All these scripts are fairly similar from what I have seen and you may want to look at javafile.com for some they may have.

PHP would be my preference ... but since I'm going to be moving the existing pages to a new site soon, I'd be willing to consider other options if something great existed in another language.
