Free comics!

So, Comixology has a ton of free issues for download, and I've been meaning to check out some of the Marvel comics. Assuming the website works long enough for me to use it (they seem to be rather overwhelmed by the traffic), anyone have any recs?

Also, Ramin Karimloo is coming to Alexandria on tour. I think I might want to go... I did just buy tickets for The Last Five Years, though... Why can't I just have ALL THE MONEY? :(
