It all depends on the quality of guitar you are after. But I'd do and have done the following.

Take some one with you that plays like you and listen to them play the guitar. You want the guitar to sound as good to the audience as it does to you. Then you play it.

Then you decide if the sound is what you want. Play a bunch that way and set them aside.

Now play them again and be aware of the fit of the guitar. Is a Dreadnaught the right fit or is a OO or OOO better. Set aside.

Now play again for the feel of the neck and frets. This is the least important of the program. All of the previous qualifiers are not changeable. The set up is. Unless the guitar is a real wreak of an instrument, the necked twisted and the intonation is so bad as to be hopeless the strings can be brought down to a playable level.

The guitar can be refretted and the finger board adjusted.

And when it's all done with if you are like me I'd settle for the Guild F-30 M or RNT.
