New or not, thank you for your post. You have made some good points, and funny as it may seem we both have done similar research in a similar method. I know have quotes from Thermwood ($100k area) MultiCam (60k area) Camtech (60k Area) Gerber Sabre ( 50k area) TechnoCNC ($35k area) Shop Sabre, Shop Bot, and EZ-Router. Shop Bot and EZ-Router look to have a lot in common, though when you talk to the Shop Bot People they share no opinion claiming EZ-Router is new on the scene. EZ-Router uses mach3 cnc win/controller, Shopbot uses their own, and Shop Sabre runs WINcnc, a controller I found on the Camtech.
When I went to the distributor to look at the camtech (my second sighting, the first was at awfs in vegas) I was pretty impressed with the ease of use of the controller. I can only imagine mach3 is easy to use as well, I just never actually seeen it run a router. The Sabre looks more industry standard all around, from the gantry layout down to the controller. I do feel more likely to go with the Shop Sabre for that very reason. It is also the only machine in the class that has an option of tool changers, although I do not need one.
What it is coming down to for me is, what am I really going to use this machine for? (wood working and sign work). How much do I think the machine will be run? (realistically 4 hours a week at best, I don't get out to the shop enough as it is let alone running the machine). So I decided money matters, a position I normally do not take when it comes to my tools.
As far as accuracy, I under stand that more is better, after all I am an American, but we are talking about accuracy and repeatablity that I can not see on my tape measure. Worst case, with most inacurate router on the market my accuracy will improve to a rediculous extent.
In summation, Shop Sabre is my current front runner.
