Lamp cord.
thanks Guy, so is this the same stuff?
I'm thinking what your link shows is bigger than 20 AWG. The link shows 1.0 mm wire, but I don't know if this is sectional area or diameter. I'm guessing it's about 17-18AWG. Regardless, it is what I've always known as 'magnet wire'.
Got a handy-dandy conversion chart in this link:

Pete I need a good deal longer than 2m...and that's all that the Bay shows....and the price isn't too cheap either.
Do you know if that above Jaycar stuff is ok?
Magnet wire is ok, but you'll need to scrape the enamel from each end to expose bare copper.
Part of the trick with magnet wire is 'dressing' it, as you'll have a pair of ungainly wires if you leave them bare.
It's worth noting that Anti-Cables are magnet wire too.
