That's a good price.
Just for fun I downloaded the trial version of Rhino 3D a couple of days ago. It's a fully functional demo so you can actually try it out. It's limited to a certain number of saves.
There's also a demo for Rhino Cam which as the name implies will produce G code and toolpaths directly from whatever you drew in Rhino 3D.
I don't have my machine done so I can't speak for how well this will work but it seems quite easy to use and there's a neat cut simulator in the CAM section.
Of course it will be a lot more than $170 ;(
Ted.
