Ok, i've read all the posts and here's my 2 cents...or 3.
An R6 is a VERY POWERFUL bike. Even the 01 and 02's have more than enough power than you'll ever need, and anybody that knows anything about those bikes realizes they are extremely 'wheelie happy' due to the power/weight design, etc. They are very well engineered and are excellent quality. I'm not saying dont start off w/ a 600cc sportbike, as I learned to ride on a 98ZX-6R and and a 01 GSXR-600. Not 'beginner bikes' by any means, you just have to respect the bike, know limits, and understand that 3 seconds of ****yness showing off for some girl or to have a 'little fun' could be the end of you and/or the bike as well. If you learn on one, just be careful.
Insurance depends upon which company you have. State Farm I know from experience is VERY cheap on bikes, as they just go by the # of CC's, not by what kind. However, they can give you cheap bike insurnace because you HAVE to insure a car w/ them as well to get the deal. Other insurance companies have pretty good rates as well, but remember, you get what you pay for. If you get full coverage for $25 a month, when you wreck your R6, they probably wont want to pay you for what its worth, as with anything else.
Bottom line is if you can afford it, do it. But, if you are getting a bike to save money, dont do it, because no matter how you crunch #'s, you won't SAVE money by obligating yourself w/ more responsibility. And first and foremost, be careful. When those girls start looking, your balls suddenly triple in size, and you feel like you've been riding to years.
