2 low-cost cameras for 3d?
Not sure what you are asking. Do you want a 2D single lens camera that has a builtin 3D feature--ala. you press the shutter as you are moving the camera left to right and it takes several pics and combines them into a mpo? Or a twin lens 3D camera?
I had a Panasonic 2D camera that did that several years ago and found the 3D to be hit or miss. I now use a Panasonic 3D1 and Fuji W3 twin lens cameras (both hard to find cheap these days). You can get a cheap used 2D camera and do the cha-cha method (take one pic, then move the camera to the right and take another and combine the two using Stereomaker). I do this with my cellphone a lot and it works fairly well. You can't have subjects that move, though, between shots.
