Aerosmith studio albums or one of their 200 compilations? 
Nine Lives, Pump (Both were like 2.99 on play.com I luuuurrrve that site) and Young Lust Anthology.
How'd you find these? I know people aren't keen on Nine Lives, but I've always liked it, "Ain't That A ****" is my fav, as for "Pump" that album is a classic! Regarded by many as their last great album. 
I own Nine Lives, and while I haven't listened to it loads, it's not a bad album from what I remember. The UK version has I Don't Want To Miss A Thing as a bonus track too.

Anyway, I've just ordered:
Jeff Buckley - Grace
Def Leppard - Adrenalize
