Used to have a larger standing order but had to drop some comics due to money... and the missus complaining...

DC
JLA
JSA
Green Lantern (always good)
The Flash (favourite is Wally... didn't think we needed Barry back)
Teen Titans (stop changing the roster dammit)

Marvel
The Avengers
The New Avengers
The Secret Avengers (a trend yes?)
The Amazing Spider-man (Favourite Superhero since I was 6 (wow 24 years?) but I kinda want to drop this... its not as good a read as it used to be... damn BND)

Everyone else
Transformers Ongoing

Still get Thor as trades. Do pick up Company wide Crossovers... unless its X-Men dominant then 'meh'...
Not as crazy as I used to be where I bought every comic connected to the Crossover (Civil War and House of M were really the last straw) so I've toned down a bit.
