to be honest i think its more the pricing on "certain" reatailers parts thats killing vinyl. some places over here are charging €12 for an ep!!!!
but not all are bad.. kinetec (for one) seems to have sensible pricing.. but thats only one i can think off off the top of my head (sure theres pleny moe.
so blame the money hungry record companies and not the artist/public deciding to go digital to try to generate a piuttance of an in come from music sales,
