My cheap one I got used is way better than what you describe. I don't use
the guides, but just follow the lines by eye.

Blade drift, vibration of the work, and movement in the plate or fence can
screw up any cut. Marking it with chalk, pencil, or the like disappears as
soon as the water hits it. It is good to score it with a hard metal device,
then follow that line. I'm sure there are good ones that cut true, but
you're talking in the upper regions price wise.
