Just got the cnc cookbook email and he mentions that he tried fusion 360 from autodesk. This is autodesks all in one cad/cam package that uses HSM express (that they bought). He didn't have good luck with it but this looks like just the thing for small shops as you can get it for $300 a year and does everything. I am downloading the demo when I get home but I encourage everyone to give it a shot and post what they think here. Seems like a no brainer to get into a package that has adaptive clearing/etc.
