Well I've been holding off for probably almost 6 months now. I'm just not enjoying buying two of everything anymore - especially with rehashes and repacks. I'm thinking I'd like to get it down to just the loose figures, I could army build, and buy just one of everything else.
I recently made the same decision as well. The rehash waves (GB & HV) were the straws that broke the Tauntaun's back and the Endor Wave (Chirpa, DSG, etc.) was the beginning of the end of collecting 2 of every figure. (1 open, 1 to covet).
I've started parting out my collection first to guys in the MN Collector group. I'll later hit the customizer group as there always looking for fodder and then eventually resorting the eBay.
Good luck on how ever you go about it.
