Model D2F-AGU-DB112 purchased for from the fine folks at www.d2fcovers.com
in May 2012. I paid $75 shipped.

It has a strap with Velcro on the end that goes across the bottom of the cab and attaches to the opposite side of the cover to hold it on. There is a tiny bit of frayed thread at the end of the strap (shown in pics) that does not affect functionality.
The DB112 I used it with was modded to have 4 extra rubber feet installed on the side opposite the handle, so it could easily be sat down while in carrying position. These extra feet put some indentations on that side of the cover (also shown in pics).
I'd put it at about an 8/10 condition.
$55 OBO via Paypal shipped.
Or trade for a Korg Pitchblack pedal.
