I have been using ZW3D (VX) for the past 18 months or so and really like it. I believe the version I have is called standard and has done everything that I have needed to do thus far. The support has been very good, nice people to deal with. A couple of my friends have also purchased the same package as we tend to share files alot. I tried many CAD programs before spending my $'s and VX just fit the way I think and work.
For a CAM program I am using SprutCam.
Not associated with the company just a happy customer.
