I'm having $600 to spend for a new acoustic. My last acoustic got medium neck and I didn't like it. I wanted thinner. Cutaway is a plus feature but not a must.
If you play electric then my ideal neck would be somewhere in between a Ibanez Wizard and Schecter C-1 neck.

you really should just go out and play a bunch of different acoustics. they are slightly more differed in their tone and playability from one guitar to another, even if they are the same model.
