Pc on a couple of Bows

Hi, had alittle search and couldn't find price's for similar items that are to date, so i'll ask in this thread.
So PC on these Bows would be much appreciated:

Gold Ebon Storm Bow Of Defense
15-28 damage
+14% damage
-5 energy
+5 armor
req 9

Gold Sundering Storm Bow Of Defense
15-28 damage
+12% while above 50
10/8 sundering
+5 armor
req 10

Vampiric Eternal Bow Of enchanting
15-28 damage
12% while above 50
3/1 vampiric
18% longer enchantments
req 12

Obviously none have good mods but could i please get a price on all three of them with good mods and without. Also I was told -5 energy is a bad negitive for an always mod, for a ranger, i expect this is true but ill ask for a second view, so please go ahead

80-120k
35-60k
35-60k
