If you have never ridden a "crotch rocket" then yes it can be difficult. The biggest thing is turning and maneuvering at low speeds. Once you get going, the bike will basically keep a straight line, turning involves more leaning than turning of the bars.
You wont get hurt if you take the time to learn how to ride, and ride safe.
I had a 2001 GSX-R 600 as my first bike, loved it. but once i was used to it i wanted something bigger. not that i needed it, that bike will haul major ass!
money wise, dont know your situation, but i would look at bikes that are a year or two old but in perfect condition. new bikes can be damn expensive (especially the 1000, which is also an expensive bike to insure). dont forget that parts are damn expensive too ( i dropped mine, repairs were outrageous).
not sure where you are located, but like here in MI where there is an off season, you can find good deals in the winter and early spring.
