Ok. I've done more research based on James' comments. He's too nice to put anybody down, but I'm not afraid to call a spade a spade. To whit, PCnC is nothing more than a website with no business behind it, though they may still take your money if you give it to them. A lot of people have lost money to this company. You can read these threads here (link goes to CNC Zone) and make your own mind up on the subject. I've written Saw Mill Creek and asked that my lists have PCnC removed from them. I'd do it myself, except the forum won't allow one to edit one's posts after a certain amount of time. I'd like to go on record to say, that rule makes no damn sense whatsoever. I'm a member of several forums like this one, using the same software as this one, and this is the only one with this obtuse editing rule. (And yes, I'm cranky today--just found out my hand will require a second surgery!)
The other company being referred to is Sidewinder. My research indicates the owner of Sidewinder is a nice guy who has gotten in over his head selling machines lacking in rigidity. Caveat Emptor.
My list is not intended as a recommendation for any of the units on it, nor is it advertising for those units. It is provided for informational purposes only.
