What accounts for Dutch Oven price variation? I have recently been looking to buy a good Dutch Oven that will last a while, and I am a little lost since there is so many options at many different price points.
I recall a few years ago I bought a cheap cast iron skillet and it was terrible, the season wouldn't last, the finish was very rough, and the edges of the pan to the bottom were not smooth which made washing very difficult; all of that was solved when I just bought a more expensive, brand name skillet.
Is the same true for dutch ovens? I find many options on Amazon for under $100, but there are also ones by Staub and Le Creuset up to $700; and ofcourse there are options at every price in between. They all seem to have the same weight in the specifications so I would assume the classic heavy lid is not a factor, would appreciate any insight into what accounts for this price variation, and if it is a notable factor.
I have owned many brands of cast iron and ceramic coated pans, here's the factors I've seen that effect the price:

Quality of materials: better quality coatings last longer and give better results
Refinement: some brands are more aesthetically pleasing, better designed, and have better finish than others. Some of these refinements may improve the cooking experience, some may just be looks
Name: This is a huge factor these days, some brands like Le Creuset have hiked up their prices enormously in the past decade to the point they are absolutely eye watering, yet their products haven't changed in design or quality

Of all these it's name that seems to have the biggest effect on price. I have some Le Creuset that I bought or got as gifts some time back, and I have since bought some department store branded ones (Linea, House of Frasier's own brand) which are 1/3 of the price. The department store ones look good, deliver good results and wear just as well as the Le Creuset ones. There are many brands to choose from, it's worth doing some research on what's available around you before you spend money.
