Well...two Azrael and Spoiler (Chase)
And the key with Kubricks I've found is to wait about 3-4 months after they have been released and pick them up as a set on eBay. Unless you want the chase, then wait a few weeks after the initial hype dies down and you should be able to pick stuff up fairly reasonably
I'm still catching up myself, there's some stuff I want but don't want to throw out $75 a crack for (like the BTTF Box Sets B, C and D) or $25-$30 for like the Shrek sets. I also want to get the Scissorhands set and I think I'll have pretty much all that I want as far older stuff goes
