... I've tried out an Orange Thunderverb 200 through an Orange 4x12 a while back and I have an Orange Micro crush. Although they're on opposite sides of the spectrum in terms of purpose and sound, the Orange "voicing" is there: very lush cleans. Do not expect Mesa tone (or hi-gain grind) out of 'em cause that's not what Orange's do but they do well for Sabbath to Kyuss-like distortion

I think Orange amps focus on end-user simplicity... you'd be surprised how much tones you can get with turning just a few knobs with these amps.
But if you can get a TT with a 1x12 cab for a good deal, definitely go for it... you're in the UK, should be easier for ya to try 'em out!
