i have many bishops that i love and an inkjecta specific that is very versitile. i would say inkjecta lines better and is all around very good machine with wide range of give adjustement. i run my bishops for everything but lining on a daily basis and love them though, just got used to the no give thing withem. no exp with dragonfly though. oh and inkjecta has two new models coming out in next three months worth looking at the v1 and v2 they look very cool!!
