Re:was cutting fabric ? now LASERs

I have wanted to do a laser cutter for years- maybe the prices are
finally getting to where I can do it.

I would like to cut wood- up to 1/8" ply max, and thin styrene plastic.
What power do I need for that?

If I found one of the Synrad lasers would it come with a lens, or are
they a separate part?

Id really like to hear more about lasers.
