Hello. I need some good advice on picking out a 12 string acoustic guitar. I do not want any electric pickups. Do not want a cutaway. Im mainly torn between a Taylor or a Martin. Im open to other suggestions but I really want a high quality guitar that I know will last me for years, and have remarkable tone. Im looking to spend around 2000$ give or take.

Any suggestions?
How about Mann? I like the sound of those. Or an Ovation?

I'm pretty sure Mann will last you forever. Not sure about Ovation though.

In your price range, a used high-end Guild would get the most bang for the buck and the most durable guitar.
