That'd be a tough order to fill, but here's some ideas:
From Crescent Reach:
Lava Sealed Marble of Mana -- may be a bit hard at 65, but can start it.
Sphere of the Ancients Wanderlust Guild Loadstone -- Charm Aug
From coru`kar Mesa:
Dorina #5: Dorina's Lament -- 4 different augs, the weapon aug, prob the best of the choices
Crystalwin Goru`kar Scout Augs - 4 different augs, repeatable quest .. 2 are extremely nice (Shielding and Striker)
Windwillow Sap Bauble From Sunderock Springs:
Emerald of the Oasis Crusader's Luckstone -- Awesome Aug for level + Progression for doing the quests.
From The Steppes:
Toegnasher's Token -- Maybe not so good?
Orb of Mystic Fury -- Easy quest for nice aug.
Chipped Fang of the Lost -- Another Progression series, so worthwhile.
From Valdaholm:
Runed Diamond -- Good faction quest too.
Ruby of Wards Vengeance Stone There's lots more. You can find alot yourself, just by going to Quests -
By Zone on the left, and picking a zone you can handle, or slightly above, as the Runed Diamond from Valdaholm is doable in the mid / upper 60s.
Other great, but long aug quests, are:
Breakdown in COmmunication Jonas Dagmire's Skeletal Hand Model XLII Spatial Temporal Oculus As well as lots of aug quests with faction, in Secrets of Faydwer expansion, but most of those are 75+ quests, however, the Face aug listed above, some parts can be done at 65.
Hope this helps.
