Just bought a Nordictrack Audiostrider. Got it home and assembled only to discover that it runs on batteries (4 D cell) or you have to purchase the power cord seperately. Their customer service tells me it is an accessory. This is a $1000.00 machine. The ads tell you about its work out programs, the fan on the console, Iift card, how resistance adjusts automatically while you are working out and its speakers that your MP3 player can hook up to, all things that require power. No where does it tell you that it runs on batteries or that the power supply is an accessory. A power supply isn't an accessory it is a necessity.
