I picked up an Australian Oilskin duster at a garage sale for rain riding. The coat itself seems to be made out of an infinite amount of fabric and can be kind of intimidating to put on, but once you button down all of the straps (it has straps on the interior to loop around one's thighs) it stays on well and provides a lot of rain protection. I kind of wish it had a proper hood though, it just has one giant cowl. I've never taken it on a very long ride either. For $20 it was a good investment.
