If you want a fully waterproof shell then I've got the Patagonia Torrentshell and would really recommend it. Really light, packs small, super waterproof, good quality. RRP about 100 but found mine for about half that.
The downsides would be not breathable - but if it's coming down hard enough to make you want to wear it while riding you'll be beyond caring - and no insulation, it's just a very thin waterproof shell.
