well there are three ways to find it.
1. look under accessories
2. click on either of the 730's and it will be listed under them.
3. click this link to access the 730 accessory page we made up: http://www.proportable.com/a730acc.html
or better yet... if you're looking at only the usb host cable..... here is a direct link:

Right now stock shows 48 of them left... it's too late to ship today, but it certainly could ship tomorrow.
