When I acquired my 1100 equipped 3-axis mill, I knew nothing about CNC. Thinking I needed it to program from my PC, I checked into the off-line software. Anilam quoted almost $400 for it (this was a couple years ago).
After a little more reading, I decided to buy a copy of Bobcad/Cam instead (Version 20) for not too much more $$$. I've had very good luck with the combination, and glad I went the way I did. In my opinion, it's the best bang-for-the-buck...at least for newbies like me.
