Sarnie, the clue is in the quoted post.... 
  
And if you read my post you dimwit you  will realise that I was talking about the system offered on the OC not the one Holdcroft is offering. I said that the system on the OC worked out at well over £600 for a system that was well over 3 yrs old, hence the CD based system. 
  
Holdcrofts system is the DVD based system, but is that really worth another £170? I don't know cos I've only used one of the systems.......
