Hey all, Happy New Year

So I got given 100 Dollars by relatives for the holidays and I'm looking for ideas what to spend it on... its all going to be Kindle versions... but so far I've got to buy the JLA run from the 90's to Infinite Crisis (I have the Grant Morrision run in hardcopy omnibus). And I got the 5 books for The Death of Superman and Final crisis: Legion of 3 Worlds and Superman and the Legion of Superheroes... but now I'm looking for additional inspiration and suggestions on what to get... so let me know what you suggest?
