This is my first post here. This looks like a great resource.

I am looking for a CNC router for cutting .125" thick aluminum and plastic (polycarbonate). I would use something like Rockler's CNC shark but I do have some tool changes that have to be made and the CNC Shark family is not conducive to that.

I don't need an automatic tool changer. Manual is fine as long as it uses collets and it is repeatable. One of the parts I am cutting is 18" x 4" x .125" (aluminum). The other is 14" x 14" x .5" Polycarbonate. There are some other parts as well but if it will make these then it will cut the others.

Can anyone make a recommendation for an inexpensive machine?

I invented a new panel saw and need to make parts for my hardware kit.

Thanks in advance.
