I don't think you're going to be able to get more than a "student guitar" in that price range. I don't know prices, but some of this depends what you want for sound. I think Córdoba or Almansa would be the best bet for pure old fashioned classical sound, but the Yamaha options will be the most consistent in terms of fit and finish and maybe intonation. La Patrie has a good reputation too, I think old strings may be the real cause of your predicament, I'd expect to find several really nice guitars form the makers you've listed in your price range - still essentially student grade instruments, in my view, but great sounding and enjoyable to play. Hope you find a decent solution without too much hassle!
