Those usually sell for more than the credit cap for F2P. Honestly, giving F2P 1 crew skill was idiotic. You can't even test out crafting with 1 profession. Unless you like to right click on a resource node.
I see a character-only unlock for 120K, and account-wide for 320K. At 420 Cartel Coins, it does seem a little high, though.
It's better if you don't get into crafting for the first character as it costs a lot of money and takes up too much time to be worthwile. I'd start crafting only at lvl 50 or with a twink after you leveled at least one to 50 to get some cash.
