I bought this one for this purpose and it seems to work. ($25) https://www.amazon.com/Expand-A-Lung-BD12512-Breathing-Fitne...

I'm curious how breathing with this device compares with breathing through the nose

It's adjustable with a screw down. In general though breathing through the nose just will not replicate the inspiratory effort required to use this device. Not even close.

You could try this instead. It has similar benefits.
