If you are looking for a high quality budget laser engraver I recommend the Ortur Laser Master 2.
Check out their official store on Aliexpress.
It is shipped partially assembled and only takes minutes to complete, and includes the newer STM32 control board and has integrated homing switches. In T2Laser just select the STM32 microprocessor option and set laser max to 1000 and you are ready to run, no drivers or firmware to install as this comes ready to go!
