I bought mine from "The Parts Place" since most everyone thought they were the best. I don't have it installed but from the looks of it, I'm not impressed. The tach is held together by 10lbs of silicone and it only has one hole for a bulb. I dont have any others to compare, but for $200 I thought I would of gotten something more professional

My advise to you-- Buy a tach with thats set up for 2 bulbs. Theres been a lot of talk how it's hard to see at night. If your going to spend the money, go for the 2 bulb...
