Laser engraving

Looking for recommendations on a Laser engraving machine. We would like to have a machine that will do engraving on the inside of rings. Adding our logo even on thin bands if possible. This will most likely be the main use. However we would like the flexibility of engraving on any surface. Engraving with a little bit of depth for logo in rings to a light etch of a design on a pendant plate is ideal.
Any recommendations would be great.
Thank you in advance.

We got the Best Built engraver through Stuller. It’s pricey for sure, but it can cut sheet as well as engrave inside and outside of rings. The only downfall so far is there isn’t much guidance for settings. Stuller has someone who will help if you call their tool line.
