How we work this out
We take the asking price of every Martin OM-21 listing we saw in the last 90 days across the marketplaces and shops we track, live or already gone, leave out listings with no price, and show the middle value. The usual range is the middle half of those prices. Asking prices are not always what the gear sells for.
