Thanks so much for your speedy reply. I have tried to make contact with Whyisthereair in the past, but it seems her website isn't working properly and I haven't managed to contact anyone. I've just tried again, with the same results.
The demonstrator who has just replied "Nik" is in Hampshire, which is about 100 miles from where I live, so too far away really. Guess I'll just hang on and see if anyone contacts me. I have phoned the number of the main website a couple of times, and they keep promising to get back to me, but , so far, I've heard nothing.
I have to admit it's kind of putting me of the Thermomix purchase all together, which is such a shame as I was quite keen. Thanks so much for trying to help me, I really appreciate it.
