I think this could be an interesting thread; I would like to start collecting some artbooks. Artbooks are great for getting inspiration and such. It would be helpful if people mention any of their favorite artists that have artbooks even if they don't have the scans. That way we can find out about new artists whose artbooks we might want to purchase.

Yusuke Kozaki has some nice work. Here's the artbook for Fire Emblem Awakening: http://www.mediafire.com/download/32xaaiwbwr1oji7/Fire+emblem+awakening+artbook.7z
He's designed characters for other series but I haven't checked for the artbooks.

I love Yasuda Suzuhito's art style. I don't have his artbooks but here's a preview/review of one: http://www.nattoli.net/entry/381/yasuda-suzuhito-and-yozakura-quartet-yasuda-suzuhitos-shooting-star-carnaval
