Someone in the German forums had one of the beta models. His experience has been relatively good so I strongly considered buying one for the race skin. IMO that should be the only reason for buying it. No digital gauge design trying to mimic analog is ever going to surpass the brilliance of the double doctorate E46 design, but what I was sorely missing at track days is the bar gauge that you get with the race skin. I don't track that much anymore though so it hasn't been a priority lately.
BTW I used to never be a huge fan of the reverse rev counter but after trying it on a V8 Vantage I've grown to quite like it.
