How do you level your turntable?


Short of buying a 400 dollar digital level, what have you found that really does the trick. I've tried various cheap bubble levels with fair to poor results.

Dougdeacon has the answer to this. I have $500- worth of levels to install fine cabinetry and I always rotate 180 degrees and halve to find dead nuts. The ONLY way to find true level with a bubble.
A 9" "torpedo" bubble level works great. $4-5 dollars at Lowes or Home depo. A torpedo level gives you a north-south, east-west and diagonal level reading at the same time.
I use digital level with great result. You can actually level to zero degree with digital level. It only gives approximate indication (hardly to zero) with bubble level. You hear the difference when you level your platter to zero degree.
