Yes, new ones are pricey...I would scrounge some totaled SLs in the boneyard for a used unit.

Yours has the digital odometer, so make sure you match up with the same type. Earlier 129s had the analog odometer.

Also, change out all of the bulbs at that time, as they are cheap and easily accessible. PITA to do so later when the cluster is back in the car!
