Actually QD Inventory ( http://www.skyrimnexus.com/downloads/file.php?id=667 ) doesn't have weight to value ratio
No, really, it has. Look at the fourth (hidden!) picture, last column (first three images are probably from the older version of this mod, without this feature). It even lets you sort the inventory by this value. However unlike the second mod you've linked, it doesn't show the value in item details.
