In your price range, I would not call the C7 your best value. The C10 is a much better instrument and within your price range. There are also lots of other good choices. Esteve, Navarro, Picado, Cervantes...to say nothing of the great used choices available here and at other places. The key factor is that we can only tell you what we might like. You have to determine for yourself what sounds best to you and what is available to play where you are located. You don't really mention where you are. With that info, the recommendations of where to look would be more specific.
