I have a mill/ Kiln drier near me. I buy what they call Kiln samples. They are used to check moisture content during the drying process. They range from 4-12 inches width and 3-4ft long all are 5/4 and cost me .75 cents each regardless of species. I have picke up some reall great deals on Walnut, Cherry, Oak, Poplar, Beech, Ash and Maple before. As said before the time it takes to resaw and mill is well worth the effort.
