Since you are in Europe I would advise a good hard look at Laney Amps (they can be hard to find in USA I am told). I have been looking for a new Amp lately and Laney seem to represent the most for your money from a highly respected company. In particular look at the Laney Cub head for a great deal on real all-valve technology if you dont need too much volume. As I recall that particular one gives you a choice of output at either 15W or less than 1 watt. It will be my bench-mark when I come to part with my cash.
Of course, if money was no object, and I wanted a lot of volume, with classic tone, I would be heading straight to a Marshall dealer.
