I emailed Christian (guy who makes them) and he said the following
Unit price is 140EUR, shipping is 6EUR, paypal is 6EUR (or via IBAN/BIC).
So at current exchange rate £114 each.
I mainly want one to stop me going for the phantom 7th gear lol.. The extra features are nice, like how many litres of fuel left and proper temp gauges are a bonus.
IF he will do a group discount (and its worth while) the only issue is getting them to you guys.
