Here's an idea: How about paying for MP3s? Well, if the idea doesn't worry you too much may I suggest a trip to Bleep.com - basically the nice people at Warp have put there entire catalgue online. Prices are resonable-ish (£1 a track, £7 an album), it's a bit slow at the moment but I've managed to buy a few vinyl only Boom Bip tracks without too much hassle.
