Cracked Rear Hub

I have a 1997 Honda xr400r with a badly cracked rear hub. I've tried to find a used replacement but they all so far just don't quite fit. Where can I order a new hub/rim for a good price? Any suggestions would be greatly appreciated.
 
There's a whole used Honda rear wheel on eBay, but it's pricey:


They also have lots of Chinese wheel sets, but I'd be a little leery of the quality.
