Hey Sundial,
Comin' at ya all the way from Sydney, Australia.
Not sure how cheap is cheap, but I can recommend the gear at Ground Effect in New Zealand. They do wicked stuff and women's specific with a good "true" fit. With your strong dollar you can get some great stuff, for what we would consider really cheap!!! Our dollar having crashed is not so great at the moment.
For example their Ice Queen jersey is a windproof fleece and really warm (my hubbie has the men's version), but our version of warm might not meet your requirements (we don't get much below 7-8 degrees celsius in the dead of winter
). This jersey with the current exchange rate will set you back about $75 USD. You could always throw a base layer on underneath for added warmth.
Hope this helps!
Keep ridin' and smilin'....
