Monocle of Perusal (ComAdv, pg. 134)- +5 competence bonus to Appraise Checks, 1/Day Identify. Also a monocle.

Stylus of the Masterful Hand (ComAdv, pg. 136)- +5 Competence to Forgery, which is always awesome since Forgery's opposing skill is Forgery

Trinket of Trickery (ComScoundrel, pg. 117)- Lets you use a skill trick you've not actually trained.

Spider Masks (Dragon Compendium Vol 1., pg 141)- Bunch of bonuses, including some skill bonuses.

Just a few wondrous items. Dunno how much use they'll actually be.
