That's a good deal of bike for not much money. If it was me, I'd take a test ride, get a mechanic to give it a once-over (check compression, signs of poor storage, etc.), and if it rides well and the mech says it's sound, jump on it.
It is a bit much for a beginner bike, but if you have decent off-road experience, you'll probably be OK. As my dealer says, you just have to exercise "more discretion than throttle".
I very much think it's a good idea to start with a less sensitive bike than this for genuine beginners, although the OP has good dirtbike experience, so has practice in fine control of his controls and would probably be OK.

Yes, it only goes as fast as you twist it, but on a supersport it's very easy for a beginner to twist it faster than he intends to. Being a bit older and tamer than the newest ones, this isn't quite so extreme, but it still has plenty of power and braking to really loop it if you aren't careful with your inputs. And one of the things that most beginners need to practice and learn is fine control of inputs.
