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.
