AJ, I love the way the Martins look: All that nutmeg-colored mahogany with the cutaway.
For me, UN-plugged, they all sound like a Jumbo guitar body with a bass neck shoved in it. I realize they are asking a lot to duplicate an upright, but I've not heard any that were even close. I would love to bluegrass with one (as I'll never be worth a dang with an upright), but they're not loud enough or bassy enough.
Plugged in, depending on the strings, you can get a half-assed electric sound out of them, provided it doesn't start howling from feedback, and that piezo harshness doesn't make me nuts.
They really need electric strings, though. I'm not sure phosphor-bronze strings are a good idea on box guitars, but they REALLY aren't a good idea on ABG's.
The only thing that came sort of close was a Larrivee I tried, and naturally they're not made any more.
I really wish somebody would make one that really works, for a reasonable price. The Halflings are fabulous (I tried one, could NOT believe how good it sounded), but for five grand, they oughta be, way past what I could justify for one.
