Repulsar,
I would definitely consider other Chronopia figures. You noted that you had some Dark Tusks - would those possibly be part of the trade at all? Otherwise, I'd be interested in:
Swamp Goblins (any, as long as it's variety of unit types)
SOKs (Aonbarr, Monarch, and new Hearthguard and Viridians)
Devout (Soulflayer, Abyss Crawler, Tormented or Damned)
Blackbloods (Goblin Swordmasters and Crimson Blades, Orc Caravan Guard)
Firstborn (Iron Guard)
I'd like to trade the entire lot of Horned Ones, at a one-to-one rate (not considering the big figs of course). So that's 35 regular sized figs and 3 larger figs.
If none of those are options for you, perhaps the 3-way trade Glenn mentioned, provided you could work something out between you guys, would work.
Let me know, as I'd love to work something out with you guys.
(As an aside, I've got a positive Bartertown reputation plus nothing but positive responses on eBay)
