How much does a button maker cost?

Nice, a layup for my first answer! I actually have been shopping around for button makers recently. As far as cost goes, it all depends on what size you want.

You can get a 1" button machine from a reputable online wholesaler like American Button Machines for less than $200. If you want bigger buttons, a 6" machine, for example, is just over a grand. And I know that places like American Button Machines have some nice systems based on if you're a beginner who will be making a small run or a professional who wants to mass produce.
