It appears that they are not offered anymore, but this one is probably pretty close:
Amazon.com: Twotrees TTS-25 Laser Engraving Machine Laser Engraver, Wood Metal Laser Engraving Cutting Machine, DIY Laser Marking, Eye Protection Design, Easy Installation(50% Pre-Install)
It cost twice as much but looks like it might have a more powerful laser and a larger work area.
