ticketing system out there?

Checkout: troubleticketexpress :)

Try this http://www.phpjunkyard.com/free-helpdesk-software.php

osTicket is bein developed again now www.osticket.com

Take a look at Trellis Desk (http://www.accord5.com/trellis)

www.osticket.com is our Choice
the best free Ticket System.

osticket is quite good from memory, although I have not looked at it for years.

Polar Help Desk is a great web-based helpdesk solution intended for small businesses who need to organize or improve their customer support. With clear user-friendly interface and rich features it becomes a perfect solution for every company. Download the free version now. It's fully featured and free for commercial usage, 1 technician and unlimited end users. For more information visit polarsoftware.com

I must recommend osTicket as well, I use it and I love it. Great design simple and effective.

I use php coin www.phpcoin.com
Pretty good, simple and can be advanced/confusing if you want it to be. :)

I've been playing with SmarterTrack from SmarterTools, the free edition comes with all the features as the enterprise version but is limited to one support user.

its actually really good, very powerful, has built in knowledge base and also a live chat facility.

check kayako, it is a good ticketing system too :)

2 problems with that:
#1 - Not free ( a requirement in the thread)
#2 - Not exactly the best support.
