That is what I have done, look at my status you will see all the thing you have saidI you really think it's a good domain, depending on your financial situation, there really isn't any harm in registering it (JUST THE ONE ... lol) and asking for feedback. You might find the feedback alone more valuable than the domain.
There is almost no avoiding buying bad domains when you start. The key is to learn from the mistakes sooner than later and limit the damages!
