I use a Marshall 1960a 4x12 cab with a PV Triple XXX 120watt head, and it does great! The stock speakers in it (Celestion G12T-75) are suited fairly well for heavier styles of music. Only downfall is the price tag. You might also want to look into a cab from AvatarSpeakers. They build great quality cabs at reasonable prices, and you can pick whatever speakers you want to use.
Expect to spend anywhere from $400-700 on a decent 4x12 cab though, new or used.
