You'll need to specify which one you're interested in because they're all different fitments on each wheel.
I'd suggest buying a new one from ebay (or somewhere similar) because used ones are very fragile. Especially when they've been installed for a few years. I know because I replaced two of them on my '96 already and they both broke into pieces when I took them out.
When I had to replace my rear sensors a few years ago, Rock Auto had the best prices, way cheaper than Honda, and less than my (now non-existant) Isuzu dealer. Couldn't find them at the local parts stores. Currently listed at $124.79
