Magazine is fairly standard, 0-2 $200 for +1 ammo. Great on the special arrow options and on smoke grenades, not useful anywhere else.
Loyalty Tattoo is $200 to give a model Bodyguard. Chuck this on Goro for a really great front line piece that can do everything, it's good value.
Climbing Claws for $100 is an ok choice compared to the later Grapple-Gun, but at the same time it's not hugely useful with sewers and grapple anyway.
Gas Mask is the same deal as Brave and the Bold in that it isn't always useful, but it costs even more here. $150 vs $100, it is even less worth taking for that reason.
Grapple-Gun at $400 is certainly expensive, but the bonus it gives is great. Definitely worth the take.
Combat Bracers is 0-2, giving models Defensive for $150. Good take on objective sitters, as they can reliably block more with it, and it's not a bad option to take, especially in a crew with such abundant funding.
Venom Dose for $100 should always go into the crew. Even though they all have rerolls to wound normally, the +1 strength is a very good bump in damage capability and cannot be missed. I personally put it on Damian (or Ichi if I don't take Damian) and I never regret it.
Precise Orders gives the Chain of Command trait for $150. This is the only place Chain of Command exists in the entire game, and it is basically a much worse version of Hidden Boss. A henchman (2VP on kill) becoming a Leader (6VP on kill) after a Leader has already died is a huge loss, and the gain from it is negligible. I would never take it.
