Good spot. Works out at £63 incl postage.
I have ordered one and have used LikSang and PlayAsia a lot. They are reliable.

BUT... because it is shipped from Hong Kong, you are liable for import duty, VAT and an admin charge. You won`t necessarily get charged this but you might do.
I don`t know what import duty is on a console (VAT is at 17.5%, and my last admin charge was £4 on £3.50 VAT.) but if I do get charged, I`ll just remember that I`m doing my bit for the schools and hospitals.

If you are unlucky and get charged, you will pay £4 + 17.5% which will still be less than buying in a shop here.
What you can do is email play-asia so they mark down the price of the console on the box or mark it as gift/prize so that you don`t get charged.
