Our cooktop mod #JSP42CKCC ser#HL281072Q was purchased 5-26-06 from Starline in Flushing, MI
It cracked across one burner for no reason-nothing spilled on it or dropped on it.
Our cost was $995 and only received two years of service (not an acceptable return of investment).
Actually we're gone 3mos each winter so the cooktop was used less than 2yrs.
Recently priced a complete new kitchen from Specialty Show Rooms in Berkley, MI for a new house(GE Monogram) WILL THINK AGAIN ON THIS.
