looking for 1000lb spectra

Today, the down rudder line on my AI snapped, at which point I was rudderless. So, it looks like it's time to replace all of the rudder lines on both of my Hobie's. Hobie use 1000lb spectra on the AI, which by my measurement, is 2mm. Rather than order the pricey replacement kit from Hobie ($95, which includes pre-tied spectra line and some plastic guide tubes that I don't need to replace), I figure I can just buy the spectra, tie it myself, and save some moolah.

Does anybody know a local source for 1000lb spectra that is reasonably priced? It seems to be about $0.30/foot online:

Better check make sure you are not voiding Hobie warranty by doing something that makes sense.
