I've just listed the following on AmiBay :-
All in good condition.
Most of those that have subscribers discs on them also have the password to undms them (only a couple of passwords are missing as far as I can remember)
I'm not willing to split - so please don't ask.
All for the reasonable price of £25.00 + P&P
Thanks, Dave G
Edited: There's 52 not 53
