If you want to spend the money, then get the Morrell Range bag target. It's more expensive than the little bags, but should last a very long time. They're a common type at many archery clubs. This would be for field points only.

For a broadhead target the Morell Yellow Jacket is a good one at a reasonable cost. DON'T shoot field or target points into this as it's bit** getting them out. This things is for bvroadheads only. Says so right on the target.

Better yet, find a local club that has things already set up for you and join it. You get the added benefit of meeting people of like mind and interests. Make new friends and shooting buddies and get a lot of good free advice if you pick the right people. This usually means the better 3D and target shooters.
