Washburn and Alvarez are great acoustics for around that price range. That one doesn't look bad at all.

I played one of those exact same ones and loved it. I also have an Alvarez PD80S dreadnought that is my favorite guitar, it's $470 new. Alvarez guitars in that price range sound very sweet, nowhere near as harsh as other brands in that price range.

Yeah, that's a great guitar, I would definitely recommend it. Check out the Epi Masterbilt DR-500M too.
