Last night I bought a small table saw, second-hand. It was about half of the price of the cheapest new one, which is about what these things went for on the local second-hand sale web portal. This morning I took some of it apart and cleaned it up. The motor works (I tested it last night). As I was cleaning it, I discovered a whole piece of wood still lodged between the blade and some of the innards, and... two steel screws also fell out. I'm so glad I took the tim to clean it before using it!
Theoretically you can adjust the height of the blade, but it requires turning the table upside down, loosening four knobs, and gently hammering at a very specific point. I think I'll just keep it permanently at a sensible setting. The blade is no longer perfectly perpendicular to the ground, and I don't have enough confidence to open up that part of the saw yet, so I fixed it by raising the one side of the table a bit. The saw is capable of sawing at an angle, but... you don't tilt the saw itself, but you tilt the working surface instead. This allowed me to set the surface perpendicular to the saw blade.
My vacuum cleaner's head doesn't fit over the table saw's dust exist (dang! where's the duct tape?). Although the table comes with a set piece to do cross cuts, it's quite small and short, and there is no railing to allow me to do longer cross cuts, so I'm going to have to think of something. There is a rip cut railing, but no cross cut railing.
Now I'm off to the hardware store in the hope that they have the same type of screws that fix the blade guide to the table -- the previous owner had all but stripped the screw heads and I was lucky to be able to remove it.
The picture below is not my table saw, but a cleaner specimen, so you can see what kind of a saw it is:
And here are the two surprises that I only discovered once I started cleaning it, turned the thing on its head, and removed the blade guide:
