Here is a link to what I bought..

they come with 18 months warranty.
The shipping price has gone up slightly, but it is still only £46 in total..
I still haven't received any customs charges, but even so, it won't be any more than a tenner.
My view is that all the kits are made in China/Hong Kong anyway, and rebadged/boxed for different suppliers. why pay more for the same thing.
