can set you up with everything except the archer mini, which you have to find for yourself (and glue onto the platform). I don't *think* he's run out of them yet.
There is a perfectly acceptable
alternate orc archer in my Alternate Sculpts thread, linked in my sig, though you'd have to paint it.
Perhaps you can track down the original, or some other acceptable alternate. And if you do find a good second choice, please let me know so I can add it to the Alternate Sculpts thread!
