Like I mentioned above, it depends on how cutting edge your product is. I can't give you any specifics but you can try contacting a Chinese supplier through Alibaba.com they will be able to give you a rough idea. I know from the downvotes I've received that I won't be wasting more time trying to convince people about their misconceptions.
As a rule of thumb, the more exotic and cutting edge your product is, the more savings you will get from mass production obviously. The JooJoo/Crunchpad is not unusual. From what I've read, it's a commodity touchscreen attached to an Intel Atom motherboard.
If your product is unsellable due to a small difference in the quantity you are able to sell, you have bigger things to worry about: namely the quality of your product. There's a reason why the cost of new products such as consoles or cpus are sky high in the beginning. Why should your company be any different?
