These guys have just been in touch with me: http://www.epicbleedsolutions.com/. They do their own Avid bleed kits for £13, I’ve seen genuine Avid kits for £40 now, and if your bike is cursed with Avid brakes, you need a bleed kit ;~) Shimano bleed kit (with syringe, which even Shimano don’t supply) for £5, complete with 50ml of Shimano mineral oil.
Also worth taking a look at their resource section where you will find instructions and videos for bleeding many different makes and model of brakes.
And just in time for Christmas!
