You could try Cotswold or blacks, who is cheaper I don't know but I have:
Brasher (now berghaus) hillmaster goretex boots (warm, comfy and waterproof)
Jack wolfskin goretex trousers and jacket
I don't use gloves so can't help you there.
I've always found that having great boots makes all the difference, if my feet are warm and dry then I'm good.
However I'm in the office permanently now
