I to was very interested in the Hoodivision shade, I actually got close to ordering it until I read the disclaimer on their website about most orders to the UK going straight to customs and then not notifying customers. I then did a bit of digging and found that on top of the cost of the shade + shipping (if you ever get it) you are likely to get charged VAT and a handling charge., This would bring the total for the shade to approximately £42.
One option I thought might be viable is if any of our american friends would be willing to buy one and then post it to the UK showing the value as under $15. when Data posted the ND filters I had them within a week and no charges. Obviously I would pay up front via paypal.
