This will cost about £500 if I look hard, is it worth it?

I am looking for a new amp and these have had pretty decent reviews...

I play styles from Indie to metal would the sound me versitile enough for this range?

No, valve Hiwatts are sexy, solid state ones aren't.

For that price, you can afford a decent valve combo, like a (used) JCM900.
