Ditto on Costco. They have consistently great quality at a good price.
Or buy them from a local farmer — you may get better quality by buying something that grew up closer to home.
One of my goals for the new year is to do an electrical upgrade to support a serious freezer and some other things. Then, get to know the guy a few miles away who has a small herd of great looking Angus breeves. And get a half of one for my new freezer.
