I've been using a wacom bamboo for over 5 years now, so i decided to upgrade to a cintiq (second hand), this things are expensive as hell but i gotta tell you m8 they're smoth as a new born's ass, the size it's not a problem at all because of the hight resolution so if size was your concern then fear no more trust me. There are obviusly other brands other than wacom but i will put my hands on fire for the quality of a cintiq, if you  had already used a bigger one like the 22'' model then this is not for you, it's the same only smaller.
