Hi Kev,

Try taking a look at Delcam's Artcam program, it's designed for people just like yourself, its easy to learn and its modular so you will only ever pay for the parts of the program you actually use.

Their practically giving it away at the moment at £99! pretty amazing when you consider that its a high quality program from the worlds largest CAM developer!
