What do you need/want? A simple airway head manikin for trauma training is Crash Kelly. That’s basically a Rescue Randy type simple manikin with an intubation head. Also, probably the most inexpensive manikin for trauma education. Less than $4000.
If you want something more high fidelity, you can rapidly climb the ladder in terms of complexity and features. Be aware that the rep will try to sell you a high fidelity manikin which is probably outside your needs and ability to effectively utilize.
There are some good mid-fidelity manikins like the Simulaids ALS stat that work great for PHTLS and ACLS, probably around $10k.
I have a fair amount of experience with simulation, ask if you have specific questions.
