Yes my friend, I have.
I was going to go for the turbo smart unit, but they are not of the same quality as the tial ones.
For a start, the valve in the turbosmart unit only opens maybe 1 cm max, which means that your flow is going to be impeded in a big way comparative to a unit that opens up to the full capacity of the valve area.
In addition to that, the turbosmart valve works in a simple fashion (and don't quote me on this, I don't know the entire specifics of it, but I have been told and shown).
Basically what the turbosmart one does, is senses the pressure in the top fo the can and opens when the pressure increases. It does not give good nor accurate boost control.
The tial one however uses two pressure inputs. One at the base and one at the top. The boost pressure goes in the top and pushes down onto the top of the piston. Basically unless the boost pressure overwhelms the pressure below the piston, it will not open. Putting it simply, it will NOT open unless the boost you require is met. It physically cannot open until the boost pressure is met. Better boost control.
Anyhow,
I thought it was worth the extra dollars alone when I saw how much the turbosmart unit opened up.
