A3 coil pack

I'm after one coil pack for my A3, does anyone know where I could get one off the internet?

Have you tried the ol' flee-bay?

I've had a look on there and there is a few, does anyone know of a proper shop?

Also, I remove a coil pack to check the type and number will it put my car into LIMPO mode?

I can't remember the guy's name fully, draco something. He has a lot of VAG stuff.
