The Aussie Butcher on Margan Avenue (part of the block of shops there) is a great place to get quality meat. Much nicer (on average) than supermarket meat from my experience, and reasonable prices. Mad Butcher sometimes does better specials (but the nearest one is Pt Chev), but the daily prices at Aussie Butcher are fair and typically below supermarket price points.
I really like the knowledge that the Aussie Butchers team have. They are super helpful and really know their stuff. Importantly, they will cut to order if you have a special request - e.g. buy a bulk block of rump steak and they'll slice it for you.
Recommended for all meat types - and they always have a great range. Try their crumbed schnitzel and sausages - they are very tasty, and always good value.
