windscreens for sportbikes

I'm looking for a clear windscreen for a 2000 R6 and I can go with one of the big names (Puig or Zero Gravity) and spend around $100, or I can grab a $35 one from "Moto Fairing Inc"

I don't want to go cheap if there's a decent reason not to, but this is a piece of trimmed vac formed acrylic... how can you screw that up, and how can it cost $100?

I'm definitely leaning toward the $35 one. Anyone know better?

thanks

It comes down to the materials they use ! The cheaper ones are not as clear or fade in sun ! Most times you get what you pay for ...IMO
