I agree with gerv's advice on rebuilding the wheel, even if just to have as a back-up. Even if you need to buy an inexpensive (but good) rim like the CR18, you can get the wheel back on the road for a reasonable cost and (the much bigger benefit) learn a bit about wheel building in the process. Having recently trashed two different rear wheels, I'm quite happy to have picked up some wheel building skill earlier.

If you do go this route, let me say that while double-butted spokes are stronger and lighter, straight gauge spokes are much, much easier to learn with on your first build.
