Another alternative is to have it rebuilt. There are a number of companies on Ebay that will rebuild. The $300 - $400 (bba-reman, 4mercedes.com, etc.) price range does not include remanufacturing the potentiometer. Beckmann will charge $800 - $1200 which includes the potentiometer. If you are going to spend that much, then get a new one. I bought one on Ebay for $400 that was already rebuilt.
