Just broke down and ordered a case of Wave... 4 I guess from HTS. The wave with Hoth Luke, CW Anakin, Vader, Wedge, Kithaba, Evazan, etc. Only $127 after taxes and free shipping, which comes out to $10.64 a figure. This gives me 3 Mauls and DS Lukes, which I guess I can trade off. And I can burn the spare Qui-Gon or something.
This leaves me with only "needing" Tarkin and a few Navy Commandos, which I can hopefully trade some of these extra Deleted Scene figures for.
