Best place to find an armrest?

[ADB]

Hello everyone. I'd really like a front armrest for my new acquired A4 Avant. One small problem, the original leather ones seem to be a fortune and the 3rd party rests look a bit dodgy. What do you all suggest? Has anyone on here bought 3rd party version, and are happy with the purchase?  Are they a pain to fit? (I'm a nightmare with measuring etc!) 

I've read something about needed a template to fit one, but all of the articles I've read on the WWW seem to have it missing....... 

Thanks ;)
