Who needs to spend $61 for a crappy piece of wood to scrape your BBQ. After a few uses, it will be really gross and all chewed up anyways. Many times I have forgotten to bring a BBQ scraper along in the trailer and have resorted to visiting my "firewood supply" to obtain a scraper to be used for the BBQ. I thin sliver of wood cut with an axe from a piece of firewood works great and the greasy remains are easily disposed of in the fire pit when I am done. And next time I need a BBQ scraper, I just slice another thin piece of a different piece of firewood with my axe.
Edit: Just as an afterthought, go to a lumber supply store and pick up a few cedar shingles. They would work great as scrapers and would be much cheaper than the Amazon version.
