Being one of the last to know brigade on the SRR/CTL front I haven't bothered looking for them until yesterday...7hrs travelling the length and breadth of my manor and I found 17 said units of which 5 are unchipped....3 of which were full. I was suprised to say the least because one of them is in a well known arcade chain. Happily, I came home £450 better off after playing others.
