PC on -2/+8 Shields

Hi, as you have probably seen in the buy forums, I have been trying to buy/collect these shields. I have recently purchased two of them:

Max Req 9 Tactics Tall Shield
-2 enchanted
+8 AL vs. Fire

Max Req 9 Tactics Shield of the Wing
-2 enchanted
+8 AL vs. Slashing

Now I have to admit these two cost me very different prices. And now I'm not sure how much these shields are actually worth. I will be lacking in funds to buy the rest if they all cost the same as what I paid for the second shield...

Thanks in advance!

5k on fire, and 10-15k on slashing.

Dang, I paid 7k for 1st one and 32k for second one, lol, guess it's not cheap to be a collector...

So did I overpay for these shields? Any other opinions?

And thanks Cottage, I should've listened to your advice, lol...

They'd definately be more valueable should the -2 be stance.
