Mastercam starts at $3300 including maintenance for 1 year.
Mastercam Mill Level 1 costs $5500 and does support some 4th axis machining.
The best part is it's Mastercam. A quality product with a reputation for getting the job done. Lots of translators (in & out). 2d design, 3D surface modeling.
No it's not as cheap as Bobcam or Dolphin. But it's much more powerful and it's upgradable.
