I would strongly recommend taking culinarian to 50 (if that is not one of your 50s) and using culinarian to get your glasses. The craft to unlock the culinarian master book is an 80 dur craft compared with 40 durability for all other classes. With the pre 2.3 fully melded accessories, after you get your book you should be able to comfortably HQ the culinarian token craft to get your glasses. Getting the glasses is key because it's basically another fully-melded item to be used by all classes. On top of that, it has more control than the max melded individual head pieces. Prior to the new 2.3 accessories, without the glasses, you were looking at having only 5 control to spare (from the perfect melds on all slots) in order to hit the control minimums for three star crafts. And you don't want to have to screw around with a bunch of expensive off-hand forbidden melds.
But yeah, be prepared to spend a lot of gil. I have crafted and fully melded and sold several of the new accessories, and on average you are looking at 600-800k gil to do so. I'd recommend watching materia prices closely for a couple weeks to pinpoint when they are usually lowest, or better yet, bond your own.
