Worldokit via eBay offers this 330-lb. Tempered Glass Digital Body Scale for $8.99 with free shipping. That's the lowest price we could find for any tempered glass scale by a buck. It displays weights up to 330 lbs. or 150kg.

Note: The seller indicates weights up to 396 lbs. and 180kg; however; the product itself has the 330/150 specs marked under its LCD display.
