I'm sure there will be lots of suggestions for very expensive gear, but if your budget is important and you don't need many features, and likem a clean but powerful sound - you can't go far wrong with the Hartle LH series (500 or 1000).
Cabs wise, there seems to be a lot more choice in some ways, and it could be argued that these will have a greater effect on your overall sound... My own experience is limited in this field, but I'm sure others will be along soon to inform you better!
