Actually the Breedlove that I liked was a Quartz OF (A style with f holes). Same good quality woods and craftsmanship, just less trim and lesser hardware. My ears tell me that archtop mandolins take a bit of time to mature, so one needs to hear the potential as well as the immediate sound of the instrument if it's being bought new. I would characterize the sound as being in the same league as my flattop Moon, though it's as different as any other compared archtop and flattop. The reason I'm interested in one is for tonal variation. I figure two equally good mandolins with different tonal properties will make me happier, if not a better player.
My guess is that you'd be happy with either a Moon or Breedlove, though the latter will be easier to find. I think the website says the Quartz OF is $999US, and I know of one for $1300Cdn, sans case.
Being a great fan of the music of Simon Mayor (he normally plays a Vanden), I've developed an appreciation for that A style archtop sound.
Let me know if you buy, there aren't many of us...
