Free wood is the best wood. The only wood I buy nowadays is wood that is native to my state, NC. Personal choice. That and plywood, I'm pretty sure they have plywood trees here. Gives me a nice choice really, but even so, I seldom buy anything except plywood. Pallets are a good source of wood, and are usually free. I have some rather nice Spanish Cedar out of one waiting for me to decide what to use it for. Check behind appliance stores, they usually have a stack of wood they will let you have for free, same with hardware stores. Imported motor cycle shops are a good source of mahogany plywood, sometimes solid mahogany, same with machine shops. And Craigslist has free wood. I can look about anytime and someone is giving away oak, gum, maple, hickory, etc. often listed as firewood. My older son works in A/C and awhile back he got a couple of bundles of new oak flooring in a new subdivision for free, the builders had it left over and were going to burn it. I got a good portion of that, and also he has some oak 4X4s he is giving me. From a hurricane years ago I got from my own place, hickory, oak, dogwood, pine, and something else I can't recall just now. Doesn't matter where you live, there are sources for free wood close by. Better it be used than taken to the dump.
