commercial toasters, tvs, washing machines, you generally can't go wrong with spending a premium for something that was built to last a LOT of use. Speedqueen makes commercial washing machines with a consumer lineup that's serious about lasting a while. Easily set me back $1600, but then looking at the build quality and 10 year warranty I was like "ok, they probably mean it".

One thing I noticed about commercial build quality: simplicity. No touch bullshit. Small LCD displays. Here's some buttons and maybe a rotating knob. knock yourself out.
