I got my ValveKing for £280 and have not had a problem with it (yet). The lead channel is not up to much, but put a Blackstar distortion pedal in front of the clean channel and you get a decent sound. And it's worth replacing the standard valves as well.
I know this isn't much help, but I own an Orange TT and Rockerverb 50, both are awsome amps. But the TT is too limited for what you are looking to do (great amp though) and the RV50 is £1000 for the head, then you need the cab. However, Sue uses the RV 50 with all of her pedal board in front of the clean channel, delay, distortion, the lot and it works well. So perhaps the Rocker 30 will do the job for you that way.
I hope you find a solution that pleases you, (good) valve amps give depth and definition that solid state can't quite do, if you can get the right one, you'll be a very happy bunny.
