Just got my Sunpro RetroLine gauge from JC Whitney. The dial is a full face dial, so it is really easy to see. It is also just a two inch face; I was worried it might be a bit small, but I drive a Ranger and now that i've installed it, anything bigger would not have worked. The full face dial is great because you can easily see how efficient you are driving despite the smaller gauge. Finally, it was cheap. I paid about 30 bucks!
