It looks like you have some solid mechanical experience, so as long as you are diligent with the maintenance, you should be fine. The Internet is full of good DIY Ducati resources, and you can even get decent prices on parts from places like CA Cycle Works.
However, as I discovered with my first Ducati, the bikes are built for performance in a very Italian way. Everything else is secondary, which means that you will be cursing the engineer that made it that damn hard for you to get to the nut or bolt you need to get to because it saved several grams or otherwise made the bike faster and wondering why you bought the bike when your nuts slam into the gas tank for the third time before you get the hang of using your knees to hang on to the tank for dear life. They can be fickle bitches as well, but if you take the time to tune them up properly (balance the cylinders, adjust the valves, set the TPS sensor if it's fuel injected) there is nothing like them on two wheels.
Good luck and God help you if you buy it - you'll be doomed for life in the best way possible ;D
