The guy that did it John, charged me £350 which included the dial faces and all LED's etc.
I went to his place and it took all day from quite early to quite late That was with me helping where I could i.e. taking apart the interior of my Zed.
To be honest John valued his time very cheaply, to get it done somewhere on a professional level I think you would be talking about a fair bit more. To my knowledge he only did his own Zed and mine although I am sure a couple of other members on here have done their own, it is not that big a job if you know what you are doing with a soldering iron but some of the LEDs particularly in places like the heated seat switches are very very small
It is by far my favourite MOD to my Zed, it is something you just take for granted but believe me when you get back into a standard one it is a sea of orange it makes the car interior look very dated imo
