It's the mold building process, Bryan. Typically a plastics manufacturer will charge around $5K for a mold such as the 200/175 Osprey insert. Then it's up to the buyers to re-coup that investment...more buyers, cost is reduced until the break even point...which takes a lot of boats. It just an't worth it, unless someone has the facility and the $$ to build one and basically donate the parts. Some people might pay $200 for the insert, but then you would need 25 buyers to recoup the cost of the mold...
