Have a look at showers Pass. I have their windproof which is excellent. I like the look of thier Elite 2.1 which gets great reviews. I can't justify the cost which is about £195 because i have a serviceable mid range Polaris which is fine really for me. Spa have them on offer for £170.
I have spent lots of money on rain jackets. But the Gore C5 Shakedry jacket is brilliant. Expensive, but totally worth it. What convinced me to get one in the end was when I looked at photos of ultra endurance riders in the rain. So many of them wear Gore Shakedry jackets. It is worth biting the bullet and spending the money. Buy one size larger than normal.
