ive used amplitube, guitar rig, izotope trash and just recently waves gtr 3. is there any others worth checking out that are good? im looking for something to use for a metal/hardcore band... any ideas?
The Simulanalog Guitar Suite is pretty good, and it's freeware.

Agreed, though, about nothing yet being able to replace a real live cabinet in a room with a mic in front of it.

Could I get some more talent in the monitors, please?
