I use the simulaids ALS stat manikin. He‘s durable and can do all the basic ALS stuff. About 6k.
ive done a lot to customize him, with some Bluetooth speakers, lots of props and wounds.
If you’ve got 20k, you can do more than medium fidelity. https://www.gaumard.com/s3040-50
It really depends on the model. My college program has a wide range of the Gaumard manikins. Our cheapest is I think $10,000 and the most expensive was around $75,000.$20k fully equipped?
