Another one for recommended Lasercutter/engraver

I looking to get another Laser to go with my Thunder Laser Nova 24. But this time I am looking for a diode laser. This would only be used for engraving. I want to get a nice black engrave which is really not possible with a 60w laser. I did have a emblaster 2 a few years ago but had a lot of problems with it mainly due to cutting. Engraving on wood was OK I am not looking to spend to much and I am happy to build a kit/
Any help would be most grateful.
