Best of luck on your quest. My copy of Village of Fear was assembled by two parts copies off eBay. For Dragon's Gate, I found a kind soul here on BGG that shipped it to me from South Africa.
Your best best is a saved search on eBay. You can also try contacting the owners who have it for trade and offer to buy the game if you don't have what they need for a trade.
A weird method I've used for rare games in the past is to contact someone with it for trade and offer to buy them an equivalent game on their want list.
I just traded for a nice copy of Dragon's Gate, so I'm on the hunt for VoF. I realize my quest may be long and dangerous, but I'm willing to try. Thanks for the tips!
