Sorry I went traveling for a week right after asking my question. I've already ordered a nylon string guitar - thank you for your detailed reply, it was very helpful as a reference.

This is a good comment! But I'll add that many classical learners use tab, and I think there's absolutely no shame there. The music is what counts, and I think rarely would someone look down on a learner.

Guitarists love other ppl learning or playing guitar!
