The truth about dies is that you get what you pay for. But like all items in a market economy, they obey the law of diminishing returns: progressively more expensive dies give you progressively less and less per extra dollar.
For coyotes and plinking, you probably don't need anything fancy. A set of Lee dies will be fine, used, if needs be. Whatever you can get for cheapest should suffice. In my experience Hornady has a pretty good quality to price ratio. RCBS is probably better quality, but they usually cost more, too. A two die set should be just fine for your purposes.
Some die manufacturer names that come to mind that will do for you, whether or not they are the best in the world:
Lee
Redding
RCBS
Hornady
Lyman
Dillon
Any of these will be as good as you need, and maybe better, depending on which model you get.
If you are thinking about getting into competition, now would not the time to buy dies for that. So don't worry about getting match-grade-this or precision-that.
