I agree, make your own broth.
I personally love to do this in winter when I can set the strained pot of hot fatty broth outside to get the fat to freeze overnight. Tied up so the critters can't get it of course.
Then I can it, I have a pressure canner which I think was well worth it, even just for broth.
It's nice having canned broth on hand rather than frozen. You don't have to thaw it and you don't have to fill up your freezer.
Hint, pressure cookers are nice for making broth too - SO much quicker. But my pressure canner was cheap and the metal seems crappy, so I have a separate smaller pressure cooker for making broth.
Another hint - you can make meat glace in a day if you use the pressure cooker. Don't cook all your meat at once, just put one layer in the cooker, cover it barely with water, then for the rest of the meat, use the previous strained results. Do 4-6 times. Then strain and reduce till it covers the back of a spoon. Without the pressure cooker you can still do this but it'll take a few days.
And of course, roast your meat before you make broth out of it if you want a nice rich broth. Try to carmelize those juices.
