I know B&M is the most famous among Porsche crowd, but I´ve heard that Vertex also sells their own short shift unit. Anyone knows this product?

Would like to hear also your opinion on the B&M vs EVO shifter. I´ve read the combination of the two is the way to go. Anyone experience any of those units?
I like the smooth feel of the original shift, was only trying to reduce the throw, I´m afraid of dropping the B&M and find it to be very hard to engage gears, will the EVO unit be smoother ?

What´s the best place to order a B&M shortshift? Thanks in advance.
