What is wrong with the 11k actuation camera? That's a very good price, are you certain there isn't a fair bit more abuse towards the body itself? If the camera is in good condition, 11k actuations is nothing.
e: For most people 10k clicks is months of use, if you consider the extra 100$ available now to put towards a new lens/other accessories, it's definitely worth it.
e: Also 100,000 clicks doesn't mean that's it's maximum lifespan, and Patrick knows that, the shutter can fail at 20k, 10k, 300, 150k, 300k, 1m, etc. It's still got a LOT of shooting left in it, most likely, and it's probably several months to an entire year of shooting, the 9,000~ difference between the two cameras.
