Another grinder that is worth considering and also has the same burr set as the Lux is this one... . It has a better grind adjustment system than the Lux and is overall, a more sturdy machine. You can buy it from here... http://tinyurl.com/3mj4b and probably a few other places. Should also ask our respected Sponsors in case they may have something thats been traded in on an upgrade as per your original question.
All the best,
