Check on what Araucanas are like in your country.
In the USA, "Araucanas" are supposed to have the ear tuft gene (that's the deadly one.) If you choose Araucanas with no ear tufts, they are fine. Breeding tufted chickens always produces some chicks with no tufts (and the breeders may be willing to sell the un-tufted chicks more cheaply, because they are not "right" for the breed.)
In England and Australia, "Araucanas" have muff/beard on their face and a crest of feathers on their head, but no ear tufts. So no deadly genes involved there.
Same breed name, same ability to lay blue eggs, different appearance and different genes.
So definitely check on what ones are in your country, before you rule out the breed. And even if the breeders have the USA-style ones with ear tufts, you can ask about non-tufted birds.
