Lasers!

Hi,

I've wanted to make a laser cutter for a while - I've got an XY table from an old plotter that'd be perfect. The only thing I'm missing is a high power laser....

For that, it seems you need:

• Laser Diode
  
• Module (copper tube to hold module, with a threaded end)
  
• Glass lens
  
• Laser diode driver
  
  

Does anyone know of a high power laser diode that'd be suitable, and anyone (preferably in the UK) that sells all of the required stuff in one sensibly priced kit?

From what I can tell you generally have to buy each thing from a different eBay seller, which seems crazy...
