They have a Gargantuan, it has Madman #1-3, Madman Adventures #1-3 and Madman Comics #1-20 and some unknown bonus content, but it's hardcover and super-pricey. I'd go with the regular Image trades, which is what I have. Volume 1 is Madman and Madman Adventures, and volume two and three are Madman Comics. I think they were either $20 or $25 each. They also have one trade for all sixteen issues of The Atomics for $25 and one for the first seven issues of Madman Atomic Comics for $20. If they're doing one of MAC for every seven, they'll be due for volume two soon, with #14 coming out next month.
