I think there's just too many items released each month for the users to keep up. I only recognized Nautilus and Gogh reed from your list.gonk
People are easily distracted by the new shinies that...older items are forgotten and hence drop in price.
The latest item I really liked is the zodiacal, but it's not something I'd consider far fetched.^^
I agree, too many items, too little time to get them all. But the truth is that Gaia evolved in many diferent ways, and many of these new items have much more quality in their design that the old ones, and they fit the avatar much better... Some of them are little, but fully detailed, etc.
It's not only the items listed in this topic, I spent almost all the year 2011 outside Gaia and returned in July this year, and lots of the items I've hoarded hoping to inflate deflated... A LOT. I lost lots of gold and made lots of bad decisions... But I learned my lesson, in the early years you could buy almost everything, it was certain it would inflate, because we had few items being released at each time, now you must have an exchanger eye and try to find the ones worth hoarding... Also, it has become a huge gamble to sell expensive items in order to buy new ones that you may like... It hapens all the time, example you sell a evolving for 500k, to buy a new item at the same price from a RIG, 3 months later the item you bought costs 150k (seriously this happens), and the item you have sold worths the same or more, but the reverse situation may also ocur.... Creepy.
