I've got one of the harbot Freight type wrenches, works well in confined spaces where you can't get strap wrench up and or into, I also have a 19" chain type wrench it works wonders when installing/removing rusted trailer balls! what seems to be harder to get is ones for small engines which have very wimpy case on the filter... twisted one by hand once which basically was a popcan thickness, and dented it with out tools!
