great stuff, that's what the club is all about.
With the difference in price, there is a bit of a reason but I don't know if it's justified (probably not), but you will find usually the $1100 is an actual factory windscreen and the cheaper ones are aftermarket. I'm sure there is nothing wrong with the aftermarket ones and they are probably better than the factory ones.
When I broke mine back in 2001 I had no choice but to get the dearest one and ecen then had to wait 6 weeks or something. Long story
