So, according to the GW website, they don't carry inks any more. I need some blue and turquoise inks. Anyone have another brand or manufacturer they recommend?

Vallejo. For all your painting needs.

Bah! Da Mighty Camel, you stole my words! ;)

But ya, I bought some Vallejo inks recently, haven't even used all of them yet (I haven't used all GW inks either), I only used their Black so far but it seems to work really well. I dilluted it with water and Future and it dried really nice, without the shine that I noticed on GW inks. I suppose the other inks will behave just the same.
