I think I'm going to have to go with Senn PMX 90's.
Bought them pretty much right after they came out in last October as I recall, after briefly trying the KSC 24's, and originally the sound felt really metallic, but now (because of burn-in or E5 that I use with them, don't know which) they sound pretty awesome. And they were practically free, standing at somewhere around 30-40€.
My only complaints are how easily they distort at high volumes (still able to get plenty of volume out of them, just missing that extra bit) and that they are fairly hard to drive for portable phones (30-something ohm).
