I got both tails togehter on eBay for $50 after shipping in very good condition (97-02). No cracks or anything, seemed like a good deal to me since everybody else wanted close to $50 for just one side even if they had like spider cracks.
IMO check out eBay too.

 

checked out ebay and the most I can find are for 100 bucks per side which is a bit pricey

 

I have one a lot cheaper, here:
