I bought a very inexpensive one, Monoprice Mini, about $180. It has a print volume of a 4.7 inch (120mm) cube.
I figured it was another skill to learn. Using 3D modeling software (I set up a free Tinkercad account) and learning how to convert files to gcode. (Cura software comes with the printer).
I may get a more robust machine as I learn more about the technology. They've really come down in price.
