Completing the collection

Looking over my battered and well-read Doc Savage collection, I find that I'm a few books short of completing it. These last few books are hard to find, and are going for quite exorbitant amounts on places like eBay and abebooks.com. I'm not looking for mint copies, just readable ones, with more or less intact covers (in bookseller jargon, Good and Very Good conditions are acceptable). If anyone spots these cheaply available in bookstores around them or actually has them and are willing to part with them for a reasonable and negotiable sum, please let me know:

Bantam Doubles:
115/116: Pirate Isle/The Speaking Stone
117/118: The Golden Man/Peril in the North
119/120: The Laugh of Death/The King of Terror
121/122: The Three Wild Men/The Fiery Menace
123/124: Devils of the Deep/The Headless Men
125/126: The Goblins/The Secret of the Su

Bantam Novels:
White Eyes
The Jade Ogre
The Whistling Wraith

I also have the following duplicates I'm willing to trade with:

1: The Man of Bronze
27: Mystery Under The Sea
30: The Flaming Falcons
40: Dagger in the Sky
81: The Stone Man
Omnibus #1: The All-White Elf/The Angry Canary/The Running Skeletons/The Swooning Lady
Omnibus #4: Mystery Island/Rock Sinister/Men of Fear/The Pure Evil

I will rebuild them. Painfully.
