Third Man drops a $75 pedal kit (soldering required). I'm not sure how many DIY people will go for this, when you can source your own parts for half the cost of this. Maybe it will get a few people into building, though, that wouldn't have otherwise.
Also, it clearly looks reminiscent of a Maestro, but I'm not sure how closely it's engineered to perform like one.
