As I've stated many times before: San Francisco Craigslist is THE place to spot the coolest sportbikes for sale. Here's a beaut of a 748R for sale:

And if you're not familiar with what makes the R worth so much more than the regular model, here is an excerpt from the Wikipedia entry for the Ducati 748:
The top of the range model was now the 748R, Ducati's racing homogolation model produced only in very limited numbers. This engine was again a derivitve of the SPS model but with more tuning. The main difference is that the R model has an overhead shower-injector arrangement compared to the 748E and S model's traditional throttle bodies, titanium conrods, titanium valves and more extreme valve timing. As such, the 748R has a larger, two-part airbox and thus the frame was also different to accommodate this. The suspension choice was Ohlins for both the rear shock and front forks, although the very first models in 2000 used Showa TiN front forks and a Showa shock absorber. The engine included a very basic slipper clutch to ensure that this would then be homogolated for use in racing and also an oil cooler.
With specs like that, $8200 sounds like a bargain!
