Thoughts on buying a laser machine vs going to a salon?

I desperately need this fuckin facial hair gone. From my quick research you can buy machines for like 2-3k and a salon is probably going to be 3-4k for unlimited or like 150~/session? Obviously a big advantage of buying a machine is being able to use it on the rest of me too which I'd have a hard time spending money at a salon for. I have savings so spending the money upfront isn't an issue for me.

Big question is are the machines you can buy as effective as salons, where should I be looking at them?
