Feel very fortunate to have a brother in law that sends several steers to the locker every year and only charges us market price for the beef and we pay for the processing. Get 200lbs or more for a 1/4 depending on how big of steer for under $3 lb. I am a steak guy so the big thing I tell our locker is don't grind or roast any of the sirloin, cut it all into steaks. Even if you don't eat them as steaks sirloin makes good stir fry or all purpose meat IMO if you need to slice or cube up some beef for something. I go back and forth on what to do with the T-Bones, they are big steaks but my oldest daughter is eating more these days so we can grill 2 of them up and eat most of them up or have little for leftover whereas 2 NY Strips aren't big enough to feed 2 adults and 2 small kids anymore. I love the filets but finding if I just leave them as T-Bones we get 2 strip steaks and 2 filets in a package basically which is perfect for our family.
Just work with your locker, if you want more roasts you probably will get lest ground beef but IMO we tell ours to put as much as they can into steaks and roasts and grind the rest and we still have plenty of ground beef out of it. Out locker also does beef sticks and summer sausage too so I usually do 10 lbs of beef sticks now too.
