Canon 100 macro lens SOLD

I'm taking the plunge and upgrading my beloved Canon 100mm 2.8 macro lens to the new L version, so I'm selling it. It seems to be selling on ebay for $475 to $500; new at BH Photo it is $639.95. I'd love to sell it via Paypal to a NPN member for $475; I'll pay the shipping. It's in pristine condition and has always been used with a B+W UV filter (B+W 415 UV Spezial 1X) which I will include. I lost the Canon lens cap, so it has a generic one.

Check out my flower photos at my Smugmug webpage below; they were all taken with this lens, mostly hand held.
