Elementalist Collectors

Where are the Elementalist Armor collectors, which piece of Armor do they trade and where might i find them in the area of Ascalon they reside in, ex:
(name), (armor piece), (area (eg, regent valley)), (eg, by the portal or next to rez shrine)

Thankyou to whoever helps me, its really pissing me of scince my manual is all wrong

www.guildwiki.org has a section on collectors for armor and weapons for each class.
