I buy my meats in bulk straight from the farm, so freezing is not an option. I find as long as its wrapped properly, and frozen quickly to a hard freeze, its just as good as fresh, at least to me. I know there are some things that it makes a difference, shellfish for example, and fish, but I find beef, pork and lamb just fine out of the freezer. The trick is to wrap it tightly so no air contacts the meat.
To defrost, I toss the frozen lump into the sink, pile things on top of it so the dogs can't steal it, and leave for the day (or overnight). I have yet to have an issue, I'm sure some people would be horrified but it works for me. I will toss ground beef into the microwave for 2-3 minutes to defrost it, but only if I'm using it in something flavourful. Microwaved meat is disgusting.
If you're getting quality meat and freezing it properly, you shouldn't have any issues.
