As always I would suggest the VOX Valvetronix amps. Cshude bought the ADVT50 amp a while back and he is in heaven about the tone and fx. ( I am making a statement on behalf of Chris now, but from chatting to him I believe it is his opinion as well. )
I play the Tonelab SE FX pedal wich is more or less the same thing but without the power amplifier, and I love it to pieces. THe FX the models etc. are all great. They do have tubes, in the pre amp at least, but I would not think that it would be a problem... I think the amp only has one tube though.
The 50 watt amp is plenty loud and it has an attenuator switch on the back of the amp. THis means you get good tone from the valve even at very low volumes... So no more bothering the neighbours when you are practising with your tube amp.
But as always it is up to you to go out play the amps and listen to what you like... That is the amp that you should get.
