Ok guys, I would like to buy my first tube amp (right now I have a Roland Cube 60 and it's good, but I want to try tubes). I want something that:

- Costs $600 or less.
- Is good for practice and maybe small-medium gigs.
- Has a nice metal distortion and maybe nice cleans.

I play mostly power metal and any type of melodic metal, and I want a sound like those:


In a few words, I don't need super brutal distortion for death metal.

Any suggestion?
$10 bucks says people will be in here screaming "Bugera," by 12 pm tmrw morning.

I can't speak much on this, sorry, metal amps aren't my thing.
