^^This. I have ordered a cluster before on Rockauto for the work truck at my previous employer. When you order it, they ask what the current mileage is on your cluster. (Or basically what you want them to program your new cluster to). Once you get your core charge back, you basically have a rebuilt AND programmed cluster for around $200. Unless you have a hookup, it will cost at least $100 or so just to get mileage programmed on a new cluster, so it's a no brainer.
