I've had his purple heart/cedar box for a while and it has been deadly.
Got to hang out with David Saturday for a little while at a "show" in Perry, GA. Have to say it was fun going through several boxes and watching David running them. He sure can run a box call. I ended up picking up one of his Macassar Ebony/walnut boxes. The one out of the bunch we picked out was a sweeeeet 'yalpy' talker. The Macassar ebony/limba boxes sounded good too.
You won't be dissatisfied with one of his short boxes.
