Well, I need a lens with a longer focal length for my laser cutter, so I need to get rid of the old one to get a bit of money for it 
CO2 Laser ZnSe Lens Laser Cutter Engraver 1" FL 0.5" (eBay item 180680758161 end time 20-Jun-11 01:14:32 AEST) : Industrial
The reason I want a longer focal length is just personal preference. This lens is perfect for laser cutters/engravers.
Says shipping to Australia, but I'd consider shipping to the US for a little more
Cheers,
Dan
