I've been wanting to buy one of these forever and finally have the money, but I can't decide between the Mandolin or Lute? I've searched on the Net for Info but it doesn't really show any differences between the two. The music I'd like to play would be Classical/Celtic/Folk/Jazz. I was wondering if anyone knew what the major differences between a Mandolin (A-Style with oval holes or F holes) and a Lute?
