You probably already know that Pinzon is Amazon's house name, usually for products they purchase from other manufacturers and then re-badge to the Pinzon name. I did a quick search on eBay for you, and there were a number of Pinzon items on there, but no 4-quart saucepan. I would advise you either (a) keep looking on eBay, and the saucepan will likely come up for sale eventually, or (b) buy an equivalent saucepan from another manufacturer. Cuisinart Classic 4-quart saucepan is similar, actually better since it is heavier, but it is priced in the $50's. However, I have seen the Cuisinart saucepan in either TJMaxx or Marshall's (can't remember which) for about $29.99. They also have All-Clads and Calphalons for discounted prices at TJMaxx and Marshall's, so you should look there.

I also think 4-quart saucepans aren't that common. Usually they're 3-quart or 3.5-quart.
