Nice scores, both of 'em

By the way, if you do need a replacement PSU, have a look at your friends' dead or unused Sony gear - I have no idea what its from, but I have a 15V Sony adaptor that not only has the exact same power specifications as the original power adaptor, but also the exact plug that you need. The only disadvantage of it is that its not an inline-style adaptor like the Apple one, its a standard plugpack/wallwart adaptor.
