A digital encoder would be the most accurate. USdigital
http://www.usdigital.com/support/glossary#glossary_opticalencoder manufactures
inexpensive encoders. With these and a step servo drive in example a Gecko
drive http://www.geckodrive.com/product.aspx?c=2&i=14456 one could build a
rotor that would be accurate to a thousand of a degree.
