You can pay more than £60 easily, but I would expect it to be boxed and lovely pristine white condition with extras like manuals etc
What is more funky today, is that you don't even need floppies to play the classics like Sensi Soccer, Monkey Island etc. - there is something called Whdload mentioned earlier. So using a HD, they boot superfast compared the good old days of disks.
Enjoy the ride!
