I've always liked that camera and since they're all used there is no issue with getting repaired in USA if needed, but the prices are such, that would replacement probably just as cheap.
You probably know this stuff already, but buy from a seller that has 100% positive feed back with hundreds of transactions and make sure that the seller accepts returns within a reasonable enough period to thoroughly test because the eBay "money back guarantee" is worthless and not honored if seller disputes the facts.
Also, use only "Verified" paypal sellers so you can get a refund if not as represented.
Otherwise, I've purchased a lot used equipment from sellers all over including Japan with mostly good results.
