Thank you Rob, you're a star, as always.
And I absolutely take your point. The bottom line is I got it cheap, I've made it work and I'm happy - I knew the risks of buying on FT and I took it on in full knowledge of what I might be in for. I'm thrilled to have got my hands on one, and now they're out of stock again I'll need a lot of persuading to send it back, believe me. On the other hand, I'm not going to lie down and let them mug me - I don't mind spending the time going through the warranty process, so I might as well give it a try and see where it takes me.
I just wanted to get my facts straight and make sure I was being fair, so I really appreciate your input.
