Save yourself any hassle and just buy a regular arrow saw . They come with a blade that will lasts for years . I have had mine for over ten years and still on the first blade.
Why buy a saw that will only cut tubes when you can have one that will cut many things? The apple saw is 250+. You can't do a thing else with it. Most don't cut more than a dozen or 2 a year.
