Best 2.5D cad/cam solution under $300

I own mach3 and lazycam that came with. I never used lazycam. Does
anyone has experienced it? How well does it perform for 2.5D work?

Also, I don't have a CAD software. Do you have a recommendation for
2.5D work? I can get Rhino for $200 and meshcam for $100 (student
price). Would you recommend these two programs together at this price?
What about Meshart?

In brief what is a good combination CAD/Cam for 2.5D at a reasonable
price.
Any suggestion is welcome!
Thanks in advance,

Christian
