Hello, I need a corset but don’t know where to get a good one under 600 pesos MXN

So here is the story, I am a cross dresser and always loved the shape a corset gives. A while ago I got from my mom a vintage faja (I don’t know the term in English, sorry) that made me go from a waist of 96 to a 80 but basically it fell apart recently and haven’t found one that did the same but I saw a corset made by Lanena corsetry that maybe could do the trick but it’s to expensive (around 1500 pesos) compared to some in Amazon (from 500 pesos or lower). thing is, they don’t look good quality and don’t want to waste my money so I wanted to ask where to get a steel boned corset on a budget that can do the same as my old faja.
