The only free one seems to be Boricufta, and it looks to be short lived. You will see a post here on their trial.

I'm new and I would like to know if there is a free server just to get previews to confirm my setup is working. I have Tekz 1.4.5 running and when I check the network s/w version I get the Tekz info listested. But when I run the client file it crashes on me. Any suggestions?
