For quality i would say look for a DLP printer which is basically an SLA printer but with something called a DMD which improves the resolution and speed. Jewelers use this to make customized jewelry which of cores has to be extremely detailed and high quality. If you want a bit more details about this just go to http://3duality.com/all-types-of-3d-printers/#3_Digital_Light_Processing_DLP

And yes DLP printers do have plastic as a printing material choice
