head gasket problem

[blue man]

hey guys

so i understand that blowing a head gasket is relatively common for the leganza. anyone know how easy it is to replace? looking at it, it doesn't look like a walk in the park. or if anyone has had a professional do it, what did they charge you? i want to know if it is worth my money to fix. the car has under 100,000 on it and i think it still has life in it. i want to save it, but not for more than $1,000.
