Survey: How much extra would you be willing to pay for a better inline brake?

4XS Update 11/3/2009 - A respected inline manufacturer is sold on the 4-wheel disk braking system (4XS for short), but like any good business, they're worried about what buyers would be willing to pay for it. To find out, I am surveying anyone who might like to weigh in. (In the dark about the 4XS? Click links below.)

QUESTION: Considering the 4XS 4-wheel disk brake technology and benefits (up to 50% shorter stops, no raised toe -- see video demo -- and no worn parts to replace), how much above current list price for standard-brake skates would you be willing to pay for a 4XS-equipped model for yourself or as a gift for someone else?
