If it's an '03, I assume you might still be under warranty depending on mileage. If not you might want to look on ebay for a used one with similar mileage or even get the Escalade one with the chrono-style gauges. Do you have oversized wheels/tires that don't match the OE rolling diameter? If so, you might want to get your new speedo cal'd to match the new rolling diameter size of your wheel/tire combo.
