I haven't looked into CUL turnins, but of all the others I've seen, GSM has absurdly cheap ones. Dragon Fang Earrings are 1/4th the cost per blue scrip of any other turnin (again, I didn't look at CUL), and Goblin Jigs are 1/2 the cost of the cheapest other one. The earrings take only one crafted mat, and it isn't even an upgraded mat (like ingot or hallowed/holy), it's a nugget, and the jigs are just an ingot and a whetstone mashed together.

I'm all for items having mats that make logical sense, but some things here are beyond that. Like, for the first two weeks of 3.0, every time my wife checked to see what the CUL turnin was (she only cares about CUL), it always required Bullion. Every time. Bullion is only obtainable by paying 40 Blue Scrips for 5 cubes. No other class has to buy items with Blue Scrips to get Blue Scrips... And they still give the same as other classes. So, 8 scrips gets you an item that you can turn in for 20. That's kinda silly, and how do you get started? =\
