Acoustic Question. I got permission to buy another guitar.........

[Bonhomme Richard]

Permission from my wife, LOL - surprising since I have 10.
I am playing a regular acoustic gig and want to get a decent, not crazy expensive, new acoustic. I have two different Ovations that I have been using but I'm not really satisfied with the sound I get playing through the PA. Having said that, I also have a D-18 Martin that I tried miking at last wednesdays gig and, though it did sound better it was limiting for obvious reasons and I was stuck at one volume level when doing leads so..................I am looking to get a new acoustic/electric. I am thinking about the Seagull (my partner plays), Takamine EF-360SC (my brother plays), or the Martin DCX1E which I have no experience with at all (can't even find any reviews).
What I am after is a good acoustic live sound. I figure I'll sell my ovation legend when I get the new guitar.
Any thoughts or help would be appreciated.
