here you go one example of the ridiculous amount of how much people want for some items
Revan's Gloves = 8,600.000 can't be too rare as there is 4 on the market right now
Revan's Mask = over 10,000.000 can't be that rare as there is 4 on the market and you can get from the vender for 100.000.
i am using the Revan gear as an example as it is one of the most sort out after gear in the game.
