I have a person auction thingie I use that does this in an automated way by doing a standard deviation from mean calc, and throwing out things that are beyond 2 (or 2 1/2 maybe?) standard deviations. it's not perfect, espcially for illiquid items (eg: without a lot of history), but works ok

This would probably be the easiest way to do it, with a minimum number of entries required before it starts filtering out the outliers,
