I just got one of those. I don't have it in hand yet, but should have it this time next week. Mine's missing the movable vise jaw / clamp, so i've got a bit of work to do on it. Really looking forward to pulling it apart and going through it - then putting it to use. Nice little machine.
Some people use standard 12" hack saw blades. They will mount in the saw, but maybe a bit fragile. McMaster Carr sells new Starrett brand blades for this saw, which are thicker and a bit taller than regular hack saw blades. I've also seen blades on ebay, though they tend to be pricey. Apparently a good blade will last a very long time.
Thanks for posting that.
