I really like Ovations, but they are, for the most part, made to be plugged in (in other words, acoustic-electrics). Mine is a great playing guitar, but the unplugged sound just isn't as full as I'd like (it is a super-shallow body acoustic though-some of the larger bowl models probably have a better unplugged sound).
I really like the Epiphone Dove. When I have the money, I'd like to get a decent full-bodied acoustic for when I play unplugged (which is more often the case right now). I considered the Dove as well as some others. Takamines are on my list as well as Seagull. A guy I know just bought a higher end Seagull and it sounds great. I'd imagine the more affordable models sound very nice as well.
