my toaster is an enameled steel tray with a steel wire grille on top of it. you put it on a gas stove burner to heat up the enameled steel enough to radiantly toast the bread resting on the grille. it's tray-shaped to catch the crumbs so they don't end up on your stove; the grille flips up so you can clean the crumbs out before they burn. a handle, made out of the same steel wire as the grille, allows you to remove it from the burner without burning your hand, and folds in for compact storage when you're not using it

these cost about US$4 locally: https://articulo.mercadolibre.com.ar/MLA-934643608-tostador-... (the price listed on that page is $3499 but currently the black-market dollar is at $950 bid, $1000 ask, so that's a bit under US$4)

but i got mine out of the neighbor's garbage during covid, gambling that it wasn't covered with cyanide or something

the electric kind you're probably talking about goes for about US$20–US$40 but i wanted to point out that there does exist a more reliable alternative
