Did you find a replacement for the one your really wanted yet, or just being hopeful you'll find one by springtime??
For yakitori or satays like this, they need to be near the heat source. Only way to do that in the KK is the sear grill, but it's difficult to reach all the way down there to flip tiny wooden skewers - and the sticks burn up too easily (even if you soak them in water first)! That's why the yakitori grill that Charles and I have works great - the skewers hang off the edge and the grate sits right on top of the charcoal.
