Yo, big-daddy-O,
I'll go along with my fellow Wash expatriates here re: the D10S. The D10 series, as Strummy points out, are their most popular seller so you quite possibly could find a good used one under 2 bills. The D10S, as shiner says, is particularly good with its solid-wood top a feature of more expensive acoustics and not easy to find at this price point.
Washburns are an excellent bang-for-the buck guitar. I've owned a few, and still have one remarkable guitar and mandolin, as well as a fine little uke bearing their little sister brand, Oscar Schmidt.
I will say, though, that laminate wood tops are easier to care for than solid tops (if you're in a particularly dry or humid climate), and while they may not 'improve' in their tone/volume with age like a solid top (if played regulalry to 'open up' the wood), they WILL remain consistent over time. That could be considered a plus by many.
If you can't find a Wash or Oscar Schmidt, you may find a used lam-top Epiphone, Ibanez, Yamaha or Takamine G-series for around 2 bills; new, they're all around the $300 - $350 range.
Whatever you find, get it with a hardshell case to protect it from calamity. It might be included in the price if used; if new, there's good cases for $50-60.
