Share 'Santha Melangeurs'

Greetings Fellow Chocophiles,   I have recently begun the process of purchasing a Spectra 40 Stone Melanger - http://www.santhausa.com/Spectra%2040%20Melanger%20Speed%20Controller.htm   Is there anybody out there on the Chocolate Life who has experience using this equipment, or who knows anyone who has?   I am receiving an extremely low level of customer service, and the warranty is very limited…
