No, I haven't bought one, but have seen them before and gave them some serious thought. But at that time, they cost a good deal more than £4. So that new price gives me reason for a further consideration.
For some applications, the 50Ω input Z will present a problem necessitating a Hi-Z to Low-Z buffer, which you mention. Depending on the required bandwidth, linearity, dynamic range, etc., such a buffer can be a considerable design challenge, which, by personal experience, I am well aware of.
