What is the price to replace a heater core in a 2001 Jeep Grand Cherokee?

I am a little concerned on the cost to replace a heater core on my Jeep. I am seeing prices that range from $300-$1000. What is a realistic price to get this done?|||$300-$1000 really most are a pain to do so it depends on what shop you call .. call three local shops wil get you a local price last one i had replace 500 bucks was still better than replacing it my self which ive done more than once|||I am pretty sure the price isn't worth mentioning because the car itself isn't worth mentioning, hope that helps :)|||500-1100 may need more parts while the dash and heater box are removed such as blend doors if they are broken
