My band is sounding pretty good right now and looking twoards gis in the near future, one problem. My 30w spider amp isn't going to cut it. I play Metalcore-ish stuff. All That Remains, Avenged Sevenfold, BFMV. I am working towards the money right now, I plan on having atleast 600 before I buy an amp. IDC if it's new or used.
6505+ 112 combo should be right up your alley. Don't worry about it being a 1x12, it's ok it'll be loud enough.
Peavey 6505+ combo.

EDIT: got beaten to it, that's what i get for multi-tasking
