I'm in an industry where we are the distributor/reseller and sell at a significant discount to "retail" customers and give even bigger discounts to volume customers. The manufacturers foot the advertising costs, including marketing dollars for certain products featured in our own ads. Marketing doesn't cost us anything but a web site and business cards.

I just had my dad's radiator recored at Superior, they're just a few miles from me. There were probably 100 radiators, about 70% aluminum, visible in various stages of production, inspection, boxing and the shipping area when we stopped in. They called us when the radiator was done and checked and repaired the heater core when we picked it up.

Their website is one of the worst I've ever seen, but it gives the critical info. They're also not salespeople, won't tell you that you need to buy that $600 radiator, but if that's the one you want they'll be happy to build it for you.

They make an all aluminum radiator with an aluminum shroud and one or two fans. It looks like it would do an excellent job.
