Many expats have commented on the low quality of cookware that is offered for sale in BA as well as the high prices of the "good" cookware. Even the asking prices for used cookware on Mercado Libre are incredibly high compared to ebay in the USA. There are a lot of items for sale on Mercado Libre that would never be offered for sale on ebay because they are in such bad shape. The shipping costs would exceed the value of the items!
In 2006 bought a few pieces of "professional" looking cookware at EASY in Palermo that were 4 mm thick. Even then an 18cm carcerola (sauce pan) cost about $30 USD and a 24cm carcerola with a handle cost over $40 USD. They had Teflon linings that are now rather worn down. I prefer unlined aluminum cookware that I can clean with a steel pad.
Yesterday I bought a 4mm thick aluminum carcerola with a solid aluminum handle on Mercado Libre for $280. It's the biggest of seven sizes that are available from the seller who is also the manufacturer in Argentina. I should receive it next week and if it is worth recommending to others I will do so in this thread. I will also buy two more (18mm/$140 and a 24mm/$180) if I like it and I will also post the address in BA of the seller's outlet.
