At first i was looking at the brand new cbr250 or the ninja 250 but then i realized that i would probably get bored of it in less than a week so i decided to look into 600's.
Your answer is right there.
Either drop the materialistic idea of riding an SS and get yourself a bike that is more insurance-friendly, or suck it up and wait until next year.
Why do you need an SS right away anyways? Other than faster acceleration and a lot more top speed, what advantages are there to an SS as a first bike? Any 250 bike will be just as fun in the turns and will get you from A to B just as well as an SS will, considering the speed limits are the same no matter what you drive.
If you want an SS as a first bike because it's "cooler", you are riding for the wrong reasons.
Remember, the first bike you buy will most likely not be your last.
250's have a great resale value because there's a huge market of new riders every year that look for them.
Buy a used one, take care of it, sell it for almost the same price next year.
Any insurance company that gives a ridiculous quote in the 10k+ area is a message that is meant to say "we don't want you as a customer, but we'll see if you're dumb enough to take the deal".
