Have a look in the rock bottom section on cotswold outdoor website. Go to local outdoor shops and cycling shops or have a look at aldi or lidl as they have some ok stuff. Goretex is expensive but honestly worth every penny. I have a berghaus goretex paclite jacket that I have used for riding, walking, holidays, and a marathon. About six years on it is like new (apart from the horse snot) and still keeps me 100% dry. DH's cheaper version is about four years old and about dead.
