Find a local tailor that can repair/replace the zippers, and you'll get many more years of use from your jacket. It's surprisingly inexpensive in most places. I have the Novara tights and a Novara jacket for most days. When it's really raining, I use actual waterproof gear (I'll have to look up the brand), but it doesn't breathe at all.

If it's over 60F and raining, I just get wet. I keep a dry pair of socks in my desk, and I'm changing everything else when I get to work anyway, so it's no big deal for me. And while we may not get quite as many inches of rain, we get a lot of rainy days here.
