I agree Scrapbook is beautiful, but I decided to....postpone picking it up for the time being. I'm a big fan of Clowes and I'd prefer associating his style to him alone. Just a personal preference. Kinda like Mignola and those who are good at mimicking his style. They're good no doubt, but I'd rather buy the original. Know what I'm saying?
Tomine's the better colorist though
I'd add Seth to that list above. Clyde Fans Book 1 is great (assuming you like the style and type of storytelling by the other artists like Ware and Clowes).
