Got a complete set of waterproof/breathable raingear from J&G Clothing including pants, jacket and helmet cover. 200.00US for everything. Seems a little pricey until riding w/t rain blowing sideways. I add a golf visor to keep the rain off my googles. Full coverage fenders are necessary as well to keep one's self and the drivetrain as dry as possible.. The main thing about riding in rain is the acceptance that one is going to get wet whether from the outside in or inside out. Make sure of having enough layers to prevent hypothermia as stated above.
