I took pottery in college as a hobby while completing my degree. I loved it so much that I have slowly been trying to put together a home studio. I would like to get a pug mill/mixer so that I can mix my clay from scratch (dry components), reclaim used clay, and use the de-airing features to save time and work. I am looking into the Peter Puggers, specifically the VPM-9SS and the VPM-20. Is the stainless steal worth the extra money (in the case of these two it would be $100 extra) and a smaller hopper? Or should I go for the bigger hopper and $100 cheaper with the VPM-20. Though I have thrown on a wheel and sculpted for years I am somewhat new to this piece of equipment and any information would be appreciated!!
