I ended up getting that 5.5w diode laser engraver from Ebay.
I didnt want to bother with the water cooling of the CO2 laser for my first one, and I needed the large engraving area this one has.

Over all I am very pleased with it. I was surprised at the fine detail and accuracy it can do.
Only odd thing so far is that, I was able to cut 2.5mm wood with about 3 or 4 passes before, and now I cant cut at all, But, it still engraves just fine.
The first pass cuts down into the wood well, but after that it just seems to make it blacker.

Here are some engravings I have done so far.
