There was a company at a stand at the Nuremberg show, offering ones from the size of a penny up to ones the size of a shoebox. I think I still have the flyer somewhere. I'll look it out for you.

Nick I have used that company, I believe Steve pointed them out to me. Delivery took a long time and payment wasn't straight forward but, I am pleased with the product.
If you want to see it or have a go perhaps our paths cans cross somewhere.
I'm glad you found that Tom, I can't find the flyer and couldn't remember their name. Aa search of UKW sisn't show it up either, I was beginning to think I'd imagined it!

My daughter got me one as a birthday present from somewhere in the US. Don't think it was very expensive, but I could ask her for the supplier's address if it helps.
Nick, I came across this company some time ago when looking for something similar, I don't know if they are expensive or what their service is like but they could be worth contacting.
