(slightly OT) copper disc source?

My perforated double-skin steel heat diffuser cost me about £4 five years ago and is still going strong.

I was going to say the same thing. But they get rusty. Given the relatively low price of chinese stainless (e.g. collanders) it's a shame they don't make a stainless one.

Why not just bite the bullet, and buy a new set of stainless steel cookware, with a copper plate on the bottom? A few years ago, I did just that. A discontinued set was found at a substantial discount for a bit over 200 dollars CDN, or about 100 quid. Well worth it too! I got 40 years of daily use out of the last ones.

One can do even better; copper cookware (not just a base plate) with a stainless steel lining (not the traditional, and has-to-be-renewed tinning).

One might alternatively view this as a stainless steel item with a head conductive cladding.

But they're "a little" pricy for me.

My thanks to Peter Fairbrother for the eBay pointer.

I now have my copper slab, 155x200x6 mm and first signs are ... impressive.

Placed over a tiny flame, I was unable (by fingertip) to notice any difference in temperature between the centre and the corners as it heated up.

Which is nice :-)

I need to add some "lugs" to keep it in place on the hob before using it in anger, and possibly some means of lifting it/moving it when hot.
