On my last bike ride I discovered that there is a farm right around the corner that sells highest quality, local, gras fed beef every Saturday.
Its really expensive though (Rib-eye 36$ per pound). Should I try it? 
Discussion
I'd be fun to just try 👍
definitely worth a try but maybe pick up some liver and cheaper cuts as well
a cow is more than a rib-eye, someone gotta eat the rest it would be a waste to feed to the dogs with all that tasty beef fat in it
Black Angus is expensive, but if you are in Germany 36$ for a pound of Rib eye does sound expensive. If they have it I would also try to buy something like mince meat, obviously if it's at a decent price.
How much is your health worth?
Definitely; high quality meat is worth it.
