I would like help gathering information about ac items, free players can get.
Ex: the guilded champions blade which is free.
Or the realm guardian set that you can get by doing the daily quests.
I ask for this because AC items don't take up inventory space as you know and I would like to have a spare set of armor(with different enchants) that I like the looks of and that doeskin take inventory space.
Apart from Valencia's code shop, these are what I suggest getting (although they require effort on your part):
Any of the Awe set (minus the blade) so cape, helm or armor as they give a 25% boost to all resources (XP, CP, Gold, Rep)
The newly released weapons in /join lostruinswar from Aranx's Farming Quests are all AC - Guardian of Spirits' Blade; Lance of Time; Avatar of Death's Scythe
Most good AC items that have bonuses require work on your part. Others are merely drops. Use the AQW Wiki, it is your best friend.
