I like this particular tach because it kinda matches the factory gauges to some extent and it's a name brand. It's relatively affordable as well. Around $100 if I remember correctly.

I really dislike seeing a Wal-Mart brand tach in a musclecar. There's an orange survivor Hemi Cuda down the road from me that is ultra cool, but the dime store tach really knocks it down a few nothces.
