I bought the single slice plastic guide which I really like. It only does one slice at a time, but I only cut when I am going to use it. I tried one of the 'luxury' bamboo slicers on amazon. I think its crap. Bamboo is soft (bamboo is actually a grass) and the knife cuts the tray very easily. Also the width of the knife grooves is pretty wide so even using the same slot makes the slices up to a 1/4 inch different. Its half way out the door for next trash day.
