I stopped using a butcher to cut my meat for me at least 12-13 years ago when I got somebody else's skanky meat. Have been cutting my own caribou and moose ever since, with a much nicer finished product. By cutting my own, I can make sure all the fat, vellum and membrane is cut from the meat. Wild game fat can actually turn rancid, even in the freezer after only a couple of months. One of the big reasons why some people complain about "gamey" taste on the meat (along with inproper field dressing/meat handling).
I make sure its just 100% meat going on the styrofoam tray. The scraps are bagged and frozen for the dogs as special treats, along with the bones. I usually take the lesser cuts of meat and have them ground for burger, etc...That I get my local butcher to do, but I always make sure I show up just after their grinder has been sterilized and I watch while it is ground. That way, I know what I'm getting. I have been looking at the larger grinder advertized by Princess Auto lately though. I like the ability to hook up my own electric motor to it. I may have to go that route, as my local butcher shop may be closing due to the death of one of the owners and the semi-retirement of his remaining partner/brother. I tried the handcrank grinder conecpt some years ago. Too much work for too little results, so that has been in the junk drawer ever since!
