What websites do you use for finding second hand hay equipment in the states?

Ok. Still looking at the steamer option for the 2020 season (depending on weather conditions here). Need to sell next season's hay to fund it first...Done some research and there 365 000 new here (Australia and in Aussie dollars). And the sea freight is reasonable as is customs charges when landed. So looking at second hand ones to import. So what sites other than tractorhouse do you use???
