Hello,
Does anyone know of any low cost or free scripts to add an events calender and/or appointment scheduler to my site?

Hotscripts has a bunch of these if you know the basics of ASP or PHP and can spend a little time plugging them into your site.

ASP Calendars: http://hotscripts.com/ASP/Scripts_and_Components/Calendars/index.html

PHP Calendars: http://hotscripts.com/PHP/Scripts_and_Programs/Calendars/index.html

Both of these sections have Free, Trial, and Pay only scripts.
