If you've got an alchemy alt that can make the raw meta gems then obviously the thing to do is get the meta recipes - money isn't spectacular, but I'm skilling off of making the metas with my alch and skilling off of cutting them with the JC, so I figure the fact that I'm getting two skill ups in 430+ skill and not losing money to boot makes it worth it.
Personally, now that the Dragon's Eye market has dried up, after I knocked out all of the meta gems, I've been working my way through the useful cuts - +STR, AGI, STA, etc - basically, the common popular and useful ones. I'm not trying to make money off of them though, just want to have them for personal/friend/guild usage.
