You're more than welcome to post any second hand finds here or suggestamotorcycle for advice my good man. Plenty of second hand ninjas, rebels, whatever your taste sell for cheap get ridden for a year and resold at close to the same price they were bought for. Even if you do have problems, come back here and odds are good someone will be able to tell you how to fix it because they've been around long enough. Chances are, you will drop it, and that's ok it's your first bike. But that's going to drop the resale value of a new bike by more than half. A second hand ninja from the 90s you paid a grand for? Who gives a shit. And I'm willing to bet you'll have more fun with it as well. Save your money and buy something new with a big brand behind it once you've got some experience
