Laser for x-carve

what is a good laser to use on my x-carve? where do I get it? Do I need any mods?

Depending on the power you need I do not think is a good idea to put a laser on something without an enclosure and fume removal.

But have you googled? the jtech kit includes all the instructions and such.

I looked at the Jtec then went with a Glowforge as I wanted to engrave and cut I am very happy with my decision the combination of the two works well together.
