Fantastic! That is $20 WELL spent!!
The Paul and Ace solo albums are fantastic. Kiss Alive is off the charts awesome. Alive II, the production value isn't nearly as good. I really liked their 80's output, and all three (Creatures, Lick It Up, and Asylum) are good, but I love Animalize. Of the three mentioned, I like Creatures best. Unmasked and Dynasty are a huge thumbs down for me. Of the first 6 studio albums (Kiss, HTH, DTK, Destroyer, RNRO, and LG), Hotter Than Hell and Rock and Roll Over are my favorites. Love Gun is probably my least favorite.
Kiss My Ass is a lot of fun. It's cool to hear other bands' takes on classic Kiss material. However, save this for last. Hear all of the original versions first before you hear them redone, because some of them are WAY off of the original, like Extreme's remake of Strutter. Of note, on Garth Brooks' cover of Hard Luck Woman, Paul and Gene are playing on the recording.
I'm with BVD on the post Love Gun Albums. Creatures and Revenge are where it's at. Revenge is just a flat-out bad-ass hard rock album.
ALSO, as an FYI, you need to change the thread title to censor the word "shit". No profanity in thread titles.
