i love
my martin d-15. it records superbly and has a beautifully balanced tone. i bought it for that reason alone, and chose the one i bought over a couple others on the rack (as well as over some of the higher-end models like an HD28V). mine spoke to me, and that was that. i don't have a pickup in it, but that's b/c i'm lazy and cheap and play my hollowbody ibanez when i need to plug in. i've been meaning to put an
LRBaggs Ibeam in it, but other things keep being higher priorities.
really, IMO, you need to look at what your needs are--do you want a guitar that kicks ass acoustically, or a guitar that kicks ass when plugged in? you usually have to pick one and compromise on the other. ovations and taks sound great plugged in, but acoustically i've never heard one that doesn't sound like ass warmed over. good luck trying to get good results with a mic in front of an ovation. and conversely, most good acoustic guitars compromise their tone when you put a pickup in it--usually b/c you're breaking the structural integrity of the wood or another of the many factors that can play into it, since they weren't *designed* as plug-in guitars like ovations.
personally, i've never liked taylors. i've played a lot from all various series, and everyone has sounded bland and lifeless to me. sure they play really easily, but IMO, it's at the sacrifice of tone. i've always thought that you give a taylor to a girl or to the lead singer to hold and strum during ballads where they need to LOOK like a guitarist.

YMMV.
I'll admit that i'm a fan of the martin sound--always have been. sure their action tends to be higher, but i'll go to my grave contending that that's a large factor in the tone--namely b/c when you lower the action on a martin, you lose some of that classic tone. some folks hate martins and feel the same way about them that i feel about taylors (except that you wouldn't exactly give a guitar with high action to a girl OR a lead singer....)

again, YMMV.
in all, no one can tell you what guitar is right for you. take a trip down to Buffalo Brothers in SoCal (LOVE that shop!!) and play 50 guitars. bring a pen and paper and TAKE NOTES! find what you like and what you don't like about all of the ones you play. i've played a few larrivees, matons, breedloves and santa cruz guitars that i've thought were real winners.....and i've played a number of martins, taylors, guilds and gibsons that i thought were dogs. again, YMWV.
no matter what though, i guarantee you that one guitar will sing to you, and when you hear it--THAT is when you put down your money......and with proper treatment, you will have a lifelong partner.
cheers,
