Until now, I've been waiting patiently for Dreamlands reprints. Well, yesterday I ended up finding 3x copies of Sleep of the Dead and In the Dread of Night on eBay for really cheap, so I guess I'm on my way to trying to collect the Dreamlands now. Journey to Unknown Kadath and Search for the Silver Key are both still findable so I'll probably order those next time I do an online order - which is whenever the War of the Ring expansion and Netrunner data pack are out.
It's only the first two packs: Twilight Horror & In Memory of Day that seem to be pretty hard to acquire now.
Now, you do have t pay a bit more unless you get lucky, but at some point you get tired of waiting
