Stig, get the analog type for two reasons:
1. A chrome analog is best for the Like because of it's retro looks.. a digital one is quite "modern".
2. Although the digital is more accurate, have to "read" the numbers on it and leave eyes off the road for a second or two... while the analog, all you have to do is a quick "glance" and you'll have an idea on the rpm... and keep your eyes on the road...
Here's a tip: Turn your tachometer in such a way that the redline is at the 12 o'clock position so with just a quick glance at wot, you can tell that you have reached the redline when your needle is pointing at 12'o'clock.
