I am assuming you are a clasical,jazz or flamenco type of finger picker then, though Willie Nelson also plays nylon.
This is what our guitar tech has to say in the Buying Your First Guitar forum, which I hope you looked through.
Most nylon string guitars do not have an adjustable truss rod because the necks are under so much less tension from the nylon strings. This is one of the most attractive reasons many new players opt for a nylon string; they are much easier on the fingers in the beginning. The necks are wider and flatter than steel string guitars. They are played with the fingers not a pick. The guitar is held over the left leg and the left foot is usually on a footstool. They are never played standing up. They always join the body to the neck at the 12th fret. They often do not have as many side position dot markers and never have dot markers on the fretboard itself. The construction method is different than a steel string typically using a ‘fan brace’ method as opposed to the ‘X’ brace method of steel string acoustics. The strings tie onto the bridge whereas steel string guitars use a ball end string with bridge pins. Can you see how different these guitars are from steel strings? Here’s another remarkable difference.
In the classical guitar market there is really no middle ground of models and prices. There are basically 2 groups; student models and performer models. Understand that in this realm, a $2000 guitar is still considered a ‘student’ model! Any classical guitar by a major guitar company like Washburn, Fender, Ibanez, etc. would be considered a student model. 99% of student models sell from $100-$1000. A serious performance instrument begins at around $4000. In the lower end of product offerings, nylon string guitars are not as loud as steel string guitars.
I believe we have some nylon string players here. Not sure that their axes are in your price range though. Your best bet is to Read reviews of them in your price range at
Musiciansfriend and see if any are more favoured than others.
