One example is the Ailunce product that retails at £389.99 with free post and packing from the Far East. The price drops even further if you buy more than one.
What has always bothered me is what happens when it goes wrong?
At this price, even if you add import duties and VAT it is way below the price of Japanese made products. When the Chinese really get into the amateur radio market (assuming they do) we can expect to see the big Japanese manufacturers really getting a shock.
I gather the UK designer did not register the design, hence the clones.
