Yep, you have to shell out the 1M creds, but it's bound to Legacy thankfully, so once you unlock it, you have it on all your characters of that Legacy. There're 6 sensor units. Each adds 2 crafting bonuses to c2, and they can be swapped. Each unit is specific to a certain type of crafting (ie-the artifice one has an artifice bonus and treasure hunt bonus, the cybertech one has a cybertech bonus and a scavenging bonus, etc). The only one I know off hand is that the artifice adds +10 artifice efficiency and +2 Treasure Hunting Crit. The sensor units are 100K each, and are bound to your legacy, so you can buy them with a high level character and mail them to a lower level character. The only crafting skill that doesn't have a sensor unit is slicing. Hope this helps you guys a little.

Okay, so I pre-ordered, but went with the free shipping from Amazon, so it sounds like I probably won't get it until December 24. That's fine, I just want to know one thing, though. If I don't redeem the code right away since I may not get it right on time, will I lose anything I've gotten up until the 22nd, or does it just mean I can't play for those few days until my CE arrives? I'm fine if it means I'll just lose a few days of playing. Figure with the holiday, I'll be plenty busy anyway. But I've already logged a bunch of time as my smuggler, and I just started a Jedi Consular. It would suck to lose that progress.
