Where to get a down coat?

After examining the ratty-tatty winter coat I bought out of desperation in first year, I’ve concluded that it no longer protects me from the cold, and would like to replace it with a down coat (or something equally warm). The only problem is, I’ve never bought down anything and I need advice on brands, stores or general tips on selecting a good coat. Help?
