Chaps, would like to have one of these fitted to whatever car I buy; where is the best place to source one, either to fit myself or ask the dealer to fit for me pre delivery - if the latter, how much labour do you think I'm looking at?

I assume the stuff found on the internet, including generic looking ones for the E39 BMW is not acceptable; are there any brands I should be looking at, and where do I find them?

The BHM car has a shortened shift - literally the shaft has been cut down, and while it shifted very nicely, it didn't have the snicky nature of a true quick shifter that I would like...

Help appreciated, as ever!
