Chris, would you mind updating the first post with the listed names you just posted as well as any and all changes that apply to the different sets and ala-carte options. IMO, one of the reasons you may be seeing less traction on some of the items is because the first post is somewhat confusing and also missing information that you've added in later posts.
Example, you included the following in another post within the thread, but it's not on the first post:
Also, if there is a special price for the "Head + Hands" package, it's not mentioned - nor whether the hands overlap with the ones included in the package above. You should also add that at $125 the heads come unpainted - that part won't help with sales though, and IMO, it's somewhat on the high side for an unpainted casting ($70 is the common price for a 20-unit run).
I'd like to help get a few more people interested in this, but when they ask me for particulars, I want to make sure I'm giving them the right info.
