I have to laugh whenever people say you can make more money from selling the materials and so it's a waste of time to craft. Who, exactly, do you think will be purchasing those mats if everyone sells them instead of crafting?
Anyhow, I have no idea who is paying those kind of prices for Grade 9 materials. I craft a ton and haven't purchased a single unit of grade 9 resources, despite the fact that for lower-grade resources I often purchase 5k units + in one shopping session.
Personally I think Armormech & Synthweaver are the worst off - profit-wise they really only can make Augments & Aug kits. And they each have HALF of the augments. That's pretty terrible IMHO.
Cybertech & Artifice seem the most diverse to me, with several things that can be made & sold quite easily. But, then, that's if you don't obsess about just the end-game items which is what most people do. *shrug*
