Here's my input,
I don't see a way to focus the laser, that means you have to get the object at the focal point by setting it on stuff and hoping it stays there. I could be wrong here.
The ventilation fan is a bathroom fan that is probably not sufficient to evacuate heavy smoke but would work fine for things that don't smoke much like ipods and laptops.
Water cooled! With an aquarium pump! In a bowl of water!
Pictures in user manual taken with cheap cell phone camera.
"Test switch" may or may not be a red dot, I don't think so and that's a very handy thing to have. After reading the manual, it may be for adjusting power output.
The software may be proprietary so you can't use files from other sources. It looks like it's pixel based so no vector graphics.
It requires XP or 2000 and a parallel port. Which could be a good thing.
On the other hand, it does look a bit sturdier than the laser linked from ebay a few months ago.
If links to outside forums are allowed, look here for a 91 page thread on this machine, it appears to have been around since 2005.http://www.cnczone.com/forums/laser_eng ... raver.html
It could be a good entry level machine if you have no plans to do vector, don't want to engrave anything taller than 2.8 inches and don't need it done quickly.
