Mike,
This looks like a good deal. I paid $300 for my spare, complete and ready to install after new tire was put on.
The thing I would have the seller confirm is if the wheel is straight. He skirts that issue, saying it's in good condition but does not specify if it's straight. Make sure that what is pictured is included - brake disk especially. He doesn't accept returns, so I'd hammer the questions and ask for more pictures.
The other thing you can do (and maybe already have) is to set up a search on ebay and have it email you when something new is listed. Use key words "FJR WHEEL" in used parts. I've found this easier than logging in everyday or week to search for something I need.
good luck,
Wayne
