there are many out there that want to take up the hobby of faceting but the machines prices are out of sight. good for he beginner and amateur there is a company in china, cncdealers, that has produced a machine with a LEE type faceting head and variable speed motor for under $500 (new)machine. sold on ebay item number 183491495656. you may want to check it out. i do not recommend a fixed speed machine. use fast speeds to cut but very slow speeds to polish. this machine also has the lift off head so you can examine your work easier.
i bought that china machine– interesting— does have a variable speed using a 24v dc motor and speed controller with a laptop type power brick. speed range ok, splash pan a bit high. has a drip bucket that looks to be made of a beer can but works good. a usable machine at $428 but not for competition stones, the price includes shipping from china, i got it in less than 2 weeks, and its a new machine. the head with protractor has no degree stop so its up to the cutter to use their eyes which they should be doing anyway to stop and match at correct degree.
