I have the 12x17" Light Pad and I adore it. It doesn't heat up like the Tracer, and (this may be just me) the paper actually sticks to the Pad by static so I don't have to tape it down and can just rotate as needed, even when working practically vertical. They're pricey, but still cheaper than any other light box of comparable size, and a lot lighter and slimmer. It was 100% worth the splurge for me.
