I've used FreeIPTV a few times. The accounts expire after 24 hours but you can make a new one every day if you want and there's no sign up, just a click of a button. I haven't looked through the channel line up much since I've only used it when there's a specific show or event I know I wanna watch. There's a shit load of channels though so worth checking out if you haven't done so already.
I also found it on the Awesome IPTV repo a while ago. Might be worth checking that out as well.
