A Pioneer BDRE drive, an LG BDRE drive, or a LiteOn DVDRW drive, in that order.
I'm leaving Samsung's DVDRW drives out because they're kinda mediocre or buggy.
Asus drives are rebadges of LiteOn, Samsung, or LG drives.
There's not really another manufacturer of full size (half height) drives.
Pioneer doesn't do its own DVDRW drives anymore (though the drives they rebadge are okay). LG's most recent DVDRW drives are also okay, but offer a very limited selection of speeds (in the event you got discs that managed to work at a lower speed). That's why I mention the BDRE drives for those two specifically.
But neither can scan, so you'd end up with a LiteOn for scanning.
