Hey Ben,
Why don't you stick with a Brit made company like Marshall or a Vox? People seem to like the Vox Av series, as well as the solid state Marshall series noted below. I'm a fan of the Vox AC-30, but that's a boat anchor to move around. If you needed to, you could also get a Vox tonelab or a Line6 pod to produce most of the effects you're probably looking for.
I hope you have as much fun as I've had,
Ben
