On James Taylor's site, he has a tutorial on tuning. The method he uses requires a tuner that displays cents. I have a tuner that works (Korg Pitchhawk G), and maybe Ander's tuning tutorial will help me settle down about perfection, but Taylor's guitars sound great and there's no place to hide a bad note in most of his work.

Anyhow, what tuners can display cents and what do I look for in the written descriptions that would tell me they can display cents?
