$1000 should land you a pretty damn nice acoustic almost anyway you slice it. My suggestion is know your price point and go try out a few different guitars and see what you like. Do you like the sound, how does it feel in your hands, does it feel smooth to play or is it a bit more a struggle. Guitars are very much about personal preference for feel and sound.
And as a side note, if you do eventually switch to electric, while having something like a Les Paul or Strat is nice, the real money should be spent on the amp. Because you can have the nicest guitar in the world, if your playing through crappy amp it doesn't make a lick of difference.
