If it is for deer stalking take a look at the mil surplus option - I've got a range of expensive coats and do wear them on occasions but the mil surplus has become standard for my deer stalking. Get a windproof smock, wash some waterproofing into it and if you find you need more waterproofing get yourself a surplus goretex jacket and wear it UNDER the smock so you keep all your pockets. Spend the cash you save on stalking trips.
