I have sets of CC, JP, Ref 2 (all the non-foiled cards), most of the Ref 1 foils (including Luke & Vader), most of the EPP/ECC/EJP sets, Everything but Palpatine from DS2, Tatooine, and a ton of random rares. I just can't bring myself to sell them.
The only thing I've done in the past 5 years is I bought one sealed booster of Reflections 1 off Ebay, and it was frigging amazing. Each pack had 3 foils instead in of 1, and I ended up getting almost the entire set including Vader (I had Luke before).
I'm just holding on to everything for now, trying to buy cheap single rares I'm missing of ebay when I have the cash so that I can get complete sets of everything.
