^ it wouldn't be the engl I'd buy solely for metal, but it'll do it. Ask MDV, he has one, and is a bit of a metalhead.
also, try to get one of the newer versions which have the v30 stock. bear in mind, a footswitch is extra (like £120), but you can make do with a cheaper 2 button one which lets you access most of the functions.
EDIT: I would say it's a vastly superior amp to the ones you've been looking at so far, though. And it's pretty versatile too.
