Help me pick waterproofs !

ProQuip is a good shout, superb value for money. I've got sunice goretex now, you can get good deals on these and I think there as good as galvin green.
 
Of the three the OP mentioned, I only have experience of Nike Stormfit, which was fantastic. I would recommend it highly.

After 4 years and a few reproofs, it's not at waterproof as it once was, so I've treated myself to a Galvin Green suit. Haven't had the chance to try it out as yet, but it's certainly top quality in terms of feel and design.
 
I've got a UA top and Berghaus Deluge trousers, the latter are not golf specific being more for walking but they are a bargain and truly excellent at keeping your lower half bone dry.
