Dave,
Mate let me say Im glad you posted that. Now I know Im not the only one. I have not been 100% certain if it was just me sensing it or if there actually really is a stutter going on !
Now, about your dash, for £150 or even less now that the dollar has got weaker, you can get your dash fixed mate. If you need help let me know, I live in Maidstone and have done my dash. I had issues with it, got it sent over to Jim Walker [nice chap in California USA]. I took lots of photo's when I took my dash out and I can give you a hand if you like to get yours sorted out.
Here is my E-mail if you want any further information about the dash situation: LS400@ardavan.co.uk
