LOOKING FOR – WP – Date/Booking Calendar

Folks, I’m trying to install a “booking calendar” for my users. Something that can be simple – yet effective. I found this one: http://onlinebookingcalendar.net/ but I gotta tell you – it’s just too darned expensive. BUT holy smokes – it sure is packed with features.

Is there anything out there that compares without the crazy price tag?
