  But what market have you seen a useful low power UV laser used in?  
High power cutting makes sense, low power has pretty low usefullness.  
Low power is generally much cheaper with bulbs, and what might use a 
lower power UV like a 3d prototyping machine is still a fairly expensive 
niche product.  Might be out there but I haven't seen much below $500ish 
used cutting lasers for UV..
