I put in a flat piece with a slot in it and got an estimate of $500.00. Then I changed the parameters to include powder coating and finishing and got nothing but errors in size, machine type etc. At first it looked great but when I got specific it got fussy. I had to choose thin stainless steel or aluminum of specific type and no brass, which was what I was looking for.
For a complex item great, for simple ones, do it yourself. Consider buying equipment. I hate to have to conform to the machine when I know the item or part is what I need and will work.
I am accomplished in DesignCad and Autocad.
