I am going to buy one I think, but when I looked at the site the price was in dollars, I assumed it had to be shipped from the us etc. It suddenly felt like I could do it later...
That's the answer for you, this is an international forum and people are probably a bit concerned about shipping(time, price, reliability), currency conversion etc.
I'd buy one now if it was a uk site...
Probably buy one in the end anyway, but still.
