How many of you photographers use a light meter?

After reading this thread it got me wondering how many of you are using a light meter.

If you have one, do you use it all the time? What brand/model do you have?

I just bought one to help with my poor exposure. Of course knowing my camera better, along with more learned camera tricks would help. Mine is a Sekonic L-358 (Got the RF module to trigger the Pocket Wizard's also, that can trigger my camera). Not sure it would actually be able to spot on the rider enough in a situation like the other thread shows where the rider is underexposed but the back ground is bright.
