if you think you'll want to stay with the hobby of rock tumbling, invest in a quality name brand. the harbor freight ones I bought new used belts up like crazy until the pulley split in half. get a used model 3-a lortone. parts are available and will run 7 days a week for years as long as you oil the bearings occasionally. be carefull, it can be addictive and you'll graduate to more tumblers and bigger ones.
