C: I'm mainly interested in learning to play rhythm guitar.
S: In that case, I'd suggest a steel-string guitar. The best one we have is the Ovation.
C: This one's a little too expensive for me. I'd prefer something cheaper for now. When I've learned to play, I might get a better one.
S: In that case, how about this one? It's inexpensive but it's still well made and easy to play.
C: Hmm. All right, I'll take it, and this book on how to play the guitar as well.
S: You should also get a couple of guitar picks.
C: Oh, right. Thanks for your help.
S: Don't mention it.
