I thgink you'll find it's more than that when you include the
photo-plotting and other tooling costs. If you can find one that is
£25 then I'd dearly like to know.

It's been a while since I knocked some pcbs up and my "local" supplier
plus an alternative have since gone to the wall. pcbpool.com who I've
used a few times in the recent past are 39 euros on 8 day delivery for
single sided eurocards including vat and tooling - 39 euros = 26 quid
Postage is a couple of quid extra though.

Doublesided one off price is 49 Euros = 33 quid

Bond the pcb copper side directly to the back of the mirror using an
appropriate adhesive. Normal slow setting epoxy would probably
suffice.

I would use a piece of thermally conductive pad such as silpad but it
ain't cheap (Farnell sell it).

I remember buying some about 10 years ago rather than using messy heat
sink compound on a processor heatsink. A piece slightly larger than
the size of an A4 sheet of paper was about 15 quid which I though a
bit expensive then - i just checked and it's now 43 quid for a 300mm x
300mm sheet! The problem with using this in the heated mirror
application is it needs to be clamped which might not be too easy to
achieve. I reckon an epoxy adhesive would work much better.
