try m and m cycles (usa) they are having a sale.
I got a Corsair for my brother from the US. Not very good quality at all. The front chrome section is held on by one small nut, and is very flimsy. It also sticks out to far and hits your knee. The SE heavy breather is much better quality, and cheaper.

I have a kuryakyn corsair air cleaner and am very happy with it.
I bought it and a 42 mikuni carb from the states when the dollar was high
and got both for under $500 landed here.
When i ride two up it does hit my knee but it does not bother me
but by myself it is great.
