I spoke with Susann at Ministeam about the price and she said D405 is on sale AND they have had issues with lost AND/OR missing parts in the D415 kit so the extra cost helps cover the hassle of selling kits. As suspected the D415 kit was out of stock. She did comment Wilesco plans a shipment soon but depending on air or boat this shipment may take some time to arrive.

I would guess people are more likely to lie about a missing piece in a kit in hopes of getting a free spare part.
