If you are going to go the Ducati route, I HIGHLY advise you to give serious thought to the 848 over the 1098.
If you want to spend more than an hour on either of those, the 848 will be FAR less punishing. Much better ergonomics, and very street capable. Don't get me wrong, the 1098 is an amazing bike, but it's murder to ride for more than a 1/2 hour. I got to do test rides on both, and after a half hour, my legs, back, and shoulders were screaming on the 1098. The 848 was a different story, as the end of the 45 minute ride came way too fast :-)
