I'm going to start collecting the 6" Black Series. I'm not going to go completest because how many versions of Luke/Han/Leia/Yoda/etc. does someone need? Some characters I really want to get are Kylo Ren, Ahsoka, Revan, Vader, Darth Maul, OK all Jedi and Sith in general, Han, R2, BB-8, Rey (hopefully with her saber), Finn, a few Clone's, a few IV-VI Stormtroopers and a few TFA Stormtroopers.

What are some of the better versions I should chase (probably on ebay) of older figures and what is a good place to get the newer figures from?
