"There are seven: [now nine, I think]

1): Farrp's 'Quivers and Fletching 2.5' mod, which adds four quivers which occupy a clothing slot, freeing up the player's left pauldron (a somewhat controversial feature found in version 2.0). And, if that weren't enough, this mod also allows the player to fletch arrows. Quiver mesh by Snakebitten.

2): 'Suran Archery Tradehouse 3.0', which sells a selection of arrows, bows and two of Snakebitten's quivers, modified to add the left pauldron for each of the original armors.

3): Snakebitten's 'Firefly Armor', which adds crossed swords and a quiver of arrows to its cuirass.

4): 'Quiver of Misty Moon' by Misty Moon, which gives Snakebitten's ubiquitous quiver model a racier, zebra-like retexture.

5) Kieve's 'Void Assassin Gear' a well-made, great-looking set of light armor that comes with a nice retexture of Snakebitten's quiver.

6): 'Ranger's Robe' by Dark Rebis, which adds a cool green robe with a backpack and a quiver of arrows.

7): 'Bottomless Quiver 4.33' by Glassboy, a quiver which allows you to summon unlimited arrows/bolts (as long as you have enough magicka for the types of quarrels that you choose). Quiver mesh by Archieopterix.

8) Also "Kyodin Armor"
