Prices of Perfect Shields

I'd like to get the general idea of what these type of shields are going for right now:

1. Aegis r8 30/-2 (stance)
2. Shield of the Wing r8 30/-2 (stance)
3. Aegis r8 -2 (stance) reduce blind
4. Shield of the Wing r8 -2 (stance) reduce blind

I dont have these, however wish to know the current prices incase i want to buy one of them ty in advance

both sell about the same range as it's the same skin....

1. 100k +5-15 ectos and up

3. 10-20k+
