I like Porcupine Tree, bought some of their stuff years ago, round Signify release, but then couldn't afford the time or money to follow their career. Now I find their back vinyl catalogue costs a little fortune. It is a nice technical band, with very heavy prog elements, but distinctive sound. On the other hand Marillion most popular records can be found and bought a Euro each, and their main audience comes from the good old 80ies. Some of their songs have not dated that well, but I do spin them once every decade.
