Thing is if I send an email to diezel, they're going to steer me to diezel, and I'm not commited to that - its just one option. Its a favourite at the moment (or it will be in a couple of months when I can comfortably afford it), but there are other amps on the cards, as well as changing what I have (new valves and speakers, basically)
I know someone that has a Mk4; I might see if I can have a muck about with it.
On the one hand, the axe-fx keeps getting good reviews, on the other it costs as much as a real amp, the soundclips arent much better than other modellers, and I want an amp, not yet another computer. Plus its principle strengths are versatility and effects, and I dont use any effects and am after one main sound that fits me and my style well, not 98427209875928437584819401294 of them - I just muck about with it and dont actually play.
