I plan to purchase an extruder for my home studio. I am a very dedicated hobby potter. I plan to use it to produce coils, primarily. I use both red and white clays, so ability to clean the extruder is important. It could be mounted on the wall or on a table. I don't need one of the large extruders with the wheel. So, experienced potters, which one would you recommend? Brent or North Star? Or another manufacturer?
