Where do you all get your driftwood?

I want to get driftwood for my aquarium, however I can not seem to find any. The petco/petsmart around me have it for sale, except they charge 30$ for a small 6 inch piece. I tried going to my local river to find some, but every single piece I found was either to big or in a state of decay. I also found some I can order off of amazon, but I don't trust that it'll look nice. I also have a dead peach tree that was cut down, but am not sure if it is safe for my aquarium, but I did get nice pieces from it. Any ideas on how to get some? Thanks!
