*** PRICE REDUCTION *** Shoestring USB Shutter Control + cable for Canon EOS 2.5mm
$129 at Bintel without a camera cable and without postage.
Asking $70 + postage (was $80)
Note: the cable has a 2.5mm jack. It fitted the Canon 350D. Not sure what other Canons that fits. But I presume a different cable is available for other cameras.
