You should try us out now! We've been using this system for all our own support for many many months and we've had 40 beta testers banging on it. Plus we have a 30-day free trial so you can play around. :)
HN won't let me reply directly to your latest reply. Weird.
This is great feedback, and I'm trying to figure out the best way to act on it. Here are some options:
1. Point to a user-facing demo (like http://feedback.uservoice.com)
2. Point to an admin-side demo where you can play with fake tickets
3. Offer a 30-day free trial (which we do, but it may not be easy to find)
