Alternative carrying case WITH STRAPS?

[steph280]

Why wouldn't Futaba put shoulder strap on a $70 carrying case is beyond me. Our flying site is a bit of walk from parking lot, and it would be nice if I can free up one hand to carry another heli/airplane to the field. Anybody have any suggestion on a good alternative carrying case? Or a source where shoulder straps can be purchased for retrofitting onto the Futaba cases?

thanks.
