Laser engraver

Hi, I'm looking to buy a laser engraver soon. I specifically need to engrave metal handle bars, I don't have a set budget yet so I was just wondering if you guys could summarize what would be a good low, mid, and high cost option that would allow me to work on long/bigger pieces? Ease of use?

I'm talking with the boss today with my findings. He likes to know the pros vs cons before setting a budget.

Plus any advice that you wish you knew earlier or your favorite thing you've learned about it in general would be immensely helpful.

Thank you so so so much
