You didn't mention how it got broken, but if it was like our's, the new one will break too. On our's, the bearing got dried out or worn in the speedo causing the needle to vibrate back and forth very quickly--the faster we drove the car, the louder the noise and the more violent the vibrating--until the needle broke. So that half of a needle might be telling you that it's time to have the speedo professionally repaired.
