Don't get me wrong, I think their quality is good but for the prices they are now asking it simply doesn't compare/compete with other brands at that price level in terms of leather, stitching, details, etc. They used to be a bit of a bargain and now they're at the opposite end of the scale in terms of value for money, so great in an outlet, less so at full price.
Saying that, I have managed to find it in that colour in Japan in the medium size for ¥ 41,800 (£269 more or less). They will ship it to the UK but at a cost of around £16 and you could be slapped with import duties so I don't know if you're interested in that, let me know and I'll link it up and explain how to use that site.
You're probably best off phoning them first to see if any shop has it in stock they usually ship them back and forth between shops at your request (well they do in Italy).
