I sold Yatima's sunglasses in Rome. I wouldn't suggest actually sitting down and hawking them. If you post a WTS message, you'd likely get lower prices. What I did was simply pay attention to the shopping channels for a WTB Omnitek Sunglasses. Running around the Rome area, I don't see one everyday, but I do get one maybe every two to three days as Yatima when running around subway / doing missions etc.
As for the Agent, I don't really intend to play Omegared anymore (agents don't work well in teams), so I'm not sure which rifles are good, but the ones with "counter-sniper" in their names seem to be popular.
Edit: The sunglasses are a vanity item without great stats, so, yes, you do have to be patient to sell them. If you really want to make money, mission for concrete cushions. Get QL 10 concrete cushions and sell them for about 300k a pair. Other good items to mission for are low QL Second-Hand Old English Trading Co., which I once sold for 150k, and one of the Windchaser rifles that buff treatment, I forget which one. That should sell for about 150k as well. Or you could hit level 20-ish and kill mobs at Temple of Three Winds. They drop maybe 500+ credits per mob, and respawn fast.
Yatima already has one QL 11 concrete cushion, so if you want to mission for a QL10-11 one for deccan, and help me transfer stuff from my alts, I'll pay you 200k.
Money is still tight for me at my level though. I have maybe 5.8 million cash, and can get about 100k per mission on Rubi-Ka, but I need to save for a yalm (about 5 million) and a full suit of Jobe armor (about 15 million).
