So you have seen those cheap ultra china lasers on ebay (sub $400). I purchased one 4 years ago. I was modifying it, and seeing what I could get out of it. Well looks like the new versions are a a bit different. Perhaps a bit better.
So I'm going to see what has changed. I have no illusions as it will be a pure hobby project again. After mucking around with the last one I purchased I was
successful, and it made for a fun toy. Non techie / non diy people probably end up using these as door stops mostly.
I have a decent china laser as well. A Redsail which has served me very well for the last 3 years, and it has more than paid for itself.
It will be interesting to me to see if any improvements have been made.
