I picked up a Belkin TuneCast FM Transmitter. I finally found one cheap enough that I could use to relay music from my Laptop or PC to a stereo system (Harmon Kardon and Inifinity speakers to be exact...) so I could have a decent sound system over the built-in speakers. I got it hooked up to my Mum's iMac right now. The problem is, all my cabled are crap, so if I bridge it like that, the sound keeps going from low volume, to high volume and back. it's downright annoying.

It's nice to have this thing. It's great to be able to hear semi-decent music again (or watch movies)
