I have 3 copies of Appetite as well, original Canadian, Back To Black Re release still in shrink, and original UK Robot Rape cover. I do have Illusion 1 and 2 but not original gatefold covers. Also Back To Black releases I believe. I also have a 12" interview picture disc, and a 7" Welcome To The Jungle w/pic sleeve. Lies, Spaghetti, and Democracy round out my GNR Vinyl though.
Suicide is one that is also on my watch list. Much like you, Im waiting till I find one and the time is right. I would also like to get my hands on a copy of Lies that doesnt have the black bar across the chick on the inner sleeve.
I dont have a whole lot of the Crue's stuff but I do have a Korean Decade Of Decadence, and a Helter Skelter 12" pic disc, among some studio releases.
