Here are the ones I have done to date:
Spoiler
The fisherman dude in Weye - I tried him, but then I have to kill the Imperial Legion dude who magically teleports into his house from the Inn to bust me. No bounty for this, but it is a pain.
The Adventurer dude - Finding him is the hard part.
A Pilgrim of a devine (OOO only) - They are hard for a low level character (they are like a marauder battle mage).
Natch at Hackdirt - Easy, but I found I first gotta zap him with a spell to avoid a bounty. Hitting him first causes a bounty. Is that a bug?
