Like others have written, Easton owns Beeman. However, while arrows are similar not very many models would be the "same". For example, there is no Easton brand that is the same as the Beman MFX Classic. Are there Easton shafts that fill the same bill (excep for appearance)? Yep.
More than a grain of salt is needed when you ask questions of some people in some archery shops. I very rarely ask the shop workers anything except 'do they have this or that'. If they don't have it I don't want to why I don't need it. For example, looking for some inserts for 1916 shafts several months ago I was told 'no one shoots aluminum anymore'. I know the majority of folks shoot carbon (among all archers not just traditionalists) but there are still plenty of aluminum fans out there.
