Around 6 months ago, i started my own business selling my handmade items, i am fortunate that my other half works on a very large CNC (he makes firedoors) and has been making my letters at work for me.

Unfortuantely it is a bit too risky when he should really be working, and eventually we would like to get one for our outdoor workshop. I have however, no idea what to look for, and was hoping if i tell you what it would be used for, others could help suggest something suitable? and the type of programme needed

MDF wooden letters roughly 6" high 1cm deep.
MDF wooden shapes - eg hearts, stars, plaques ect

would also like to do thicker freestanding letters, cubes and other thicker shapes.
possibly engraving into stone, this is just an idea however i am not sure the same machine can be used?

I hope this is enough info, the only thing i havnt included is a budget, becauaw dont really know how much we are talking, obviously the cheaper the better, but does the job i need it too.

Thanks a million guys
