I picked the Lyman Turbo Twin tumbler. It came with 2 bowls, 1 large and 1 small. Midway had the best price on it. It works real well but don't let the add fool you when it says they're quiet. I have no problem hearing it from the basement when I'm watching TV. As for separating the media and shells, I went to Walmart and bought a flat bottomed plastic kitchen strainer and a plastic oil drain pan for about $5. It works well but I still have do dump each shell. The drum type separator might work better on large quantities.
