Just thought we should big up http://www.p4tv.com.
I am a little biased, as Ian B and I have commented on a few shows in their catalogue. However, this site is awesome. For £15/year, you get access to kickboxing, Muay Thai, boxing and MMA events, including OMMAC, Fight Ikon, Cage Conflict, etc.
Fucking awesome really and well worth the money!
(PS I've not been asked to do this, just thought everyone should know about them!)
