Your threads remind me of my very first Warren threads here on the boards maybe 7 or 8 years ago where I picked up a whole mess of Vampirella and a few Eeries and Creepys as a bonus (could've even been you but I'm too lazy to go back and find the threads). Since I collect mostly GA now, I don't typically read the books that I buy, but any time I buy a Warren, I read it once I open the box.
I'm actually not sure why I've never really pursued full runs of these mags. There aren't many things cooler for fans of horror comics.
Also, for any Warren fans that haven't read Bill Schelly's book 'Empire of Monsters' that follows Jim Warren's career, you should really try to track it down. It's a great history of his publishing empire and has a ton of great stories as well as the history. I know I'm likely preaching to the choir here, but ya never know.
Sorry for the thread hijack - Can't wait for the mags!
