Good tube amp for around $500?

I play metal, my favorite bands are black label society, pantera, and bloodbath (little bit of a stretch from the other two huh?) anyway, I have about 500 dollars, I was looking for a tube combo amp or stack for around five hundred us dollars. I need one that fits my style and is at least 30 watts. and at most 120. I have a schecter hellraiser c-1 fr with emg 81/89, a digitech rp150 multi effects pedal, a dunlop crybaby kirk hammet wah, and what seems to be an older model of a boss g-10 multi effects pedal. I want to be able to get very heavy tones much like black label society or the tones like from bloodbath's song, eaten http://www.youtube.com/watch?v=UBfoMgllphs thanks!
