FS: 8 speed Shimano cassette $25 OBO

I just bought a set of wheels and it came with an 8 speed shimano
cassette in a 13-23 configuration. It is either an Ultegra or Dura
Ace version, but I am not sure which. Looks almost brand new. Very
little wear showing at all. This guy had not ridden the wheels in
years.
I can send a picture of the cassette to interested parties. I'm asking
$25 shipped or best offer.
You can email me at onrhodes at yahoo dot com.
I will only ship within the continental US.

Thanks,
-Pete
