If you're making a 1000 boards, saving $.10 on a connector makes you $100 more. They may not be inferior connectors. They may just be produced in larger quantities or they otherwise get better pricing. The dimensions may also be better fit for the existing design without having to recreate masks for etching the circuit boards.Quote

I'm guessing that different RAMPS manufacturers use different terminals? Would the Molex terminals called for in the RAMPS wiki be about the best quality going? Without having many connectors to make a comparison I assume the cheaper poor quality ones would be lighter, weaker and made from inferior plastic for the housing? That would be the standard way to make a cheaper product.
Also, Molex is just a brand name. Saying that a Molex connector is better suited for a job doesn't mean anything unless you state which Molex connector.
