You don't have to buy a brand new 4pls. You could easily cut cost by prototyping a regular 4pl. I didm't say i was going to buy a drop down from another company. I said i was going to buy one from whoever made one first. I'm tired of waiting and will pruchase one from any company that decides to manufacture one. You could be that company. Btw pretty sure it's free to sketch up a CAD drawing of a 4pl dropdown. That would be a better way to convince people than showing product we've already seen.
