i see your point about supporting British paintball suppliers but, when i ordered my first strap i asked KM and they didnt have a UK supplier and so i presumed the same for my 2nd. Also you dont pay any tax if its under £36.
Theres also the pain of having to wait for UK suppliers to get the new gear in stock, give me one with the stuff i want in stock when i want it, and i'll buy from them everytime.
