I'm not aware of another board with that action. But also, even though the TP40L is a light feeling keyboard to play, the TP40 mechanism itself is on the heavier side, so it couldn't be used in any super light boards. For comparison, look at the Nord Piano 5 and Nord Piano 2. The 88 key versions use a version of the TP40 that weighs only a bit more than the TP40L, and these Nords weigh almost exactly the same as each other, about 40 lbs. But the 73-key version of that action (in the NP5) still weighs about 34 lbs, while the 73-key action of the heavier feeling but lighter hammer TP100 action in the 73-key version of the NP2 only weighs about 24 lbs!
