There are some good tutorials here on SolidCam.
Take your time when making your choice.
Just another suggestion: It's a very competitive game in the CAM business, ask for 30 or 60 day trials with fully functional software. Ask for post processor files for your machine(s), then try them out on your applications. If you were going to spend 15k on a used car, you would test drive it right? So, put the the ball in the CAM sellers court. With a slowdown in manufacturing coming, they should be very cooperative.
