Best NMO mount?

[WRTC928]

I've decided to install a permanent NMO mount on my car. On the principle of "buy once, cry once" I want to get something that will provide good service until the car gives out. I'm requesting recommendations for brand and type. Aaaaand GO!

In the past, I have had good service from Larson and Laird brand NMO hole mounts.
