Really solid line that's gotten even solider over the years. If you can wade through some subpar art in a few of the early books, it's worth going through the entire line from the beginning of the relaunch (except Shadowman but even that has it's moments). They do a connected universe perfectly right, without making things too strained or hard to follow. Just super good stuff.
The best are Archer and Armstrong, Harbinger, Quantum and Woody. All the newer books (the valiant, timewalker, imperium, divinity) are off to fantastic starts too. Just close your eyes and click "add all to cart".
Actually, I'm pretty sure CMX has some super reasonable starter bundles. Probably even some free #1s.
