I dont really have a favorite as I've put a few different brands and styles in various vehicles. There are just so many options! I did just put one of these in my 91 B250. Bosch SP0F000025 Sport II 2-5/8" Tachometer
It attached perfectly to the far left side of the dash and seems to read correctly. My only complaint so far is the built in light is pretty dim, but the bulb is switchable so I'll probably drop a little LED in there at some point.
