well first off you can't legally import one into the country , and if your parents don't have some form of defence they won't either as i doubt (could be wrong) either place would 2 tone it for you (shudder) , airsoft world were selling in the uk and only place i think i have seen one , there is a thread some place where folks were discussing it , think the end all of it was it still needs the same work done inside as the vfc does to make it good. 
UN company did have a good deal on them a while back but not sure its still on but the shipping was about $140 bucks as its heavy then there is the import duty as well 
A key thing to remember and factor in when buying from abroad, (apart from the VCRA requirements), is that you will have to pay 20% VAT on the total cost, (i.e. the combined cost of the item and the shipping cost), plus anything from £13 for the shipping companys 'handling fee'.
tbh I've found very few overseas offers that are worth the hassle when you can get the same item in the Uk for a relitively small additional cost, which can be worth it for the ease of getting it fixed if something goes wrong.
Last time I checked airsoft world had sold out.
First and Only shop have got a BAR in stock for £300, thats in the Uk...
See website below for details
I have one. Its big, heavy and fun. I had a little work done on mine before i used it so can't really say how they are out of the box. The 180 round mags are a bit annoying for a support gun so i bought 4 extra which is fun changing
