Ask yourself what their incentive is to make it cheaper. The market probably won't increase by much with a slightly lower cost, but it increases considerably when you improve the capability. For many people, a e.g., 30% larger work envelope along with a smaller feature size can be worth 200% higher cost.

Then again, I'm comparing it to milling machines and lathes; perhaps the market for low end 3D printing is sufficiently different that what I know doesn't apply.
