Thanks guys, I think I'll go for one of these conductive pens, as the only replacement keyboard on ebay at the moment is $80 without shipping :-o, plus you never know when something like that could come in handy again.
It's pretty annoying having my Amiga lying in pieces because of one button, just after I cleaned the thing up and put it back together :roll: so I'll try and get one asap, thanks :lol:
