If you knock cut 3d off and go with a Gecko 540 and 3 steppers you will not save much if any but the Shark comes with cut 3d. What are you going to use for 3d cutting? I have a 48 x 96 table and also use Aspire for my cam software I use Autocad for my cad program and also run a Biesse at work. I do a lot of cutting for sign shops and a display house on my machine. I just am saying that you are not including every thing in your price.
