Oh, you know me! I can't resist a new product! I came across this Tsukineko All-Purpose Ink Workstation on sale, and immediately bought it.
The inks come in bottles and you dip the Fantastix blending tools into them, and use the blending tools as though they were pens. I decided to use the inks alone without any added line work.
No dripping. You do have to dip your Fanastix fairly often, but not so often as to be annoying, though I believe I'll work smaller in the future. I think these would be good for coloring rubber stamps or zentangle tiles.
