I am in the middle of building a plasma cutter xyz table and was wondering if it is possible or practical to use a Laser rather than a Plasma ?
Does anyone know where I can get a reasonable cost Laser

Well, since you a building a plasma table then you will be cutting metal.  If you are going to cut only 1mm sheet a ~300+ watt laser will do the trick at a price of about $7,000 +/- 2K for good working one.  If you need to cut thicker... just ad $$$.  Look around on the web for used machinery and alike.
