I started doing some archviz jobs this past year, even though my background is in sculpture, and I originally thought I would be using V-Ray for Sketchup, so I went ahead and bought a license for it. However, I've since found that using Blender and the Cycles render engine is easier for me.
So, that said, I'm selling my V-Ray v2.0 license and dongle. If you're interested, I'll post the link to my ebay post where I'm selling it. I'm pricing it to sell. Cheers!
