I am a high school wood shop teacher and I'm putting together a paper for administration in my school to try and get a CNC router. Information seems to be difficult to find online, so I would like to call upon the wisdom of this forums community. I am looking at any advise you might be able to give; such as, where to start looking, any personal experience, pricing etc. I am looking at all sizes, from desk top to 4x8 and maybe bigger if the price is reasonable, this all depends on how much money I can get.
