Well, a couple years ago, I was looking at a Taylor dreadnaught, and a very similiar Martin model. The Taylor was going for $1200, the Martin for $1300.
I couldn't hardly tell any difference, so the guy at the shop told me to close my eyes. He played both. And as I still couldn't hear a difference, I chose the Taylor.
Of course just last year I bought a Martin too...so whatever.
Just try them both see what you think.
