There are tenderizers and there are cubers. I have an electric cube machine like the one I operated in the meat industry for 35+ years. The cube machines are expensive. I got mine at an auction for $250. Hobart makes the best. Check at a restaurant/meat co. supply outfit..I'll bet Spokane Restaurant Supply has one. You can buy a hand tenderizer of around $25---has three rows of "needles" and is on a spring type frame. I use one to tenderize my steaks here at the Lodge. Hope this helps.
