Go with a F4i 600 Honda or the all new CBR600 RR that is the best 600 ever!
if you must go with a 750 the best one will always be the suzuki, and the new one is awesome dude!
Hang around some older riders and learn from them, and ride with them to learn how to stay alive on the streets, riding no matter how old you are is always a learning experiance, and experianced riders know to be willing to learn more.
Never ride in the center of the 2 track in the road it's called
"the oil drip dust and nail groove" right where every motor drips it's oil and all the dust and debris collect, I watch so many harley riders ride right in it and riders who have not learned about it's danger.
Ride with a strategy of self preservation! It's you the bike your riding and the road and it users who might kill or mame you!
Learn to ride in both of the tire tracks and when to choose wich one is safer for other people to see you, such as when approching a hill you are generaly safer when in the right track as you crest the hill because of the other vehicles in the oncoming lane could be over the double yellow and hit you, I have seen so many harley riders ride side by side over hills and oncoming vehicles almost hit them, you think they would learn that strategy and stagger themselves as well.
Riding in the Right Track also allows Oncoming Traffic to see you better when somebody in the Oncoming Traffic is About to Pass vehicles, the may jump out and not see you when your in the Left track, so many riders stay in the Left track when Oncoming Semi Trucks are coming towards them, this is downright stupid!! they are asking for trouble in the form of wind gust, a flying rock or debris, or a miscalculation of the oncoming truck drivers wheel.
Self Preservation Tactics must be paramount when riding a motorcycle, just use common sense and learn from other Smart Riders who can teach you something new!
Get a 2007 suzuki 750 gixxer dude and have fun!
