USA - 150/152 mm square hub cranks

I am looking for a sturdy set of 150/152 mm square hub cranks. They don’t have to be new but need to be in good condition. I don’t want cranks that someone has been using to do crank grabs.

I have a set of Torker LX style cranks and they are too flexible. I would like something stronger for my 26-inch MUni.
