Agreed. The giant oversized harcovers are my favorite. The ones for Y, The Last Man, Wasteland, The Walking Dead and the Spawn Origins ones are really really well done. I'm sure I'll add Sandman to that list too. I ordered the Absolute Vol. 1 and saw pictures of it online and it looks gorgeous.
As for other things....
CHEW. Holy shit, this book is fucking weird. Main character is a cop who gets psychic visions of whatever he eats. So, he eats an apple, he gets a vision of people picking it, he knows what pesticides were used on it, where it grew, etc. He eats a hamburger.... Well.... He doesn't eat meat much.
This also means he's one hell of a detective, if he doesn't mind gnawing on the bodies of the dearly departed that is. The first paperback is fairly cheap, and I'm sure you could read the first issue online somewhere too. Highly recommended.
SECRET WARRIORS. This book needs a little bit of previous knowledge to fully enjoy, but it's not necessary. Nick Fury is no longer the head of SHIELD. At the end of Secret Invasion, Norman Osborn took the kill-shot on the Skrull queen, and was named head of the newly created HAMMER (the remnants of SHIELD). Nick and his team of secret warriors, and Dum Dum Dugan and a bunch of Howling Commandoes go to war not against them surprisingly, but against longtime enemies HYDRA for reasons I wouldn't dare spoil here.
Almost done with the first volume, also highly recommended.
