If you're still looking for a set of TOS Vegas Convention boffs, and don't have/want to post a pic of yourself at a con, here are two codes up for grabs:
Rightchere
and
Ovahheah
The prices are severely inflated (thanks to people who don't know how to bid like adults), but at least the first auction includes the two older exclusive boffs too (The Doctor from Voyager and Leeta/Mirror Leeta)
I hounded both these sellers to get a code at the con, so you're welcome :P
