Welcome back!!! Have you just won the lottery? Those machines are certainly ideal for woodworking and sign writing. New machines like that are very nice, but expensive. If you are just starting or expanding a business It may be better to consider starting with a used model first - like dipping your toe in the water. You can always upgrade later if necessary, but at least you will have had the chance to see how you get on with the cnc (I'm sure you will love it) and perhaps have made some money to justify the expenditure. I am not trying to tell anyone how to run their life, just advising a little caution. Whatever you decide to do I wish you the best of luck with your venture. G.
