Looks like
these guys have them. I guess they're not easy to find... btw this site posts the actual dimensions of the interior of the case, and not the official dimensions listed on all the other sites.
A buddy of mine has a DSD case, and while it's a really slick case, I prefer the TKL bag. More padding, hard top, heavy-duty hardware and stitching, flap over the zipper, etc.
Here are the cons of the TKL bag:
-Shoulder strap that unzips to become backpack straps isn't perfect.
-Pockets are too small to hold sticks or sese.
-It's ugly.
Other than that, it's really well designed and has help up really really well for me. It even has a "foot flap" on the bottom. You can flip this out, and step on it while you pull your drum out so you aren't wrestling with the bag. Even though I don't use it, I thought it was a good idea.
